    An Electrochromic Polymer Based on Cyclopenta[2,1-B;3,4 Effect of a Single Atom Alteration on the Electrochemical and Optical Properties of the Polymer Backbone
    (Elsevier Science Sa, 2020) Tutuncu, Esra; Varlik, Bengisu; Kesimal, Busra; Cihaner, Atilla; Ozkut, Merve Icli; Icli Ozkut, Merve
    An electrochromic polymer, namely "poly(2,6-(3,3-didecyl-3,4-dihydro-2H-thieno [3,4-b] [1,4]dioxepin-6-yl)-4,4-dioctyl-4H-cyclopenta[2,1-b;3,4-b']dithiophene)" (P1), was electrochemically synthesized successfully, and its electrochemical and optical properties were investigated. The band gap of the polymer P1 was calculated as 1.77 eV with -5.45 eV Highest Occupied Molecular Orbital (HOMO) and -3.68 eV Lowest Unoccupied Molecular Orbital (LUMO) energy levels. The polymer P1 is bluish purple when neutralized and highly transparent greenish purple when oxidized. This color change was observed around 1.4 s between its redox states and optical contrast ratio was found to be as 49 % and 53 % with 234 cm(2)/C and 239 cm(2)/C coloration efficiencies at 590 nm and 634 nm, respectively. Moreover, the properties of this polymer were compared to its analogues and also during this comparison the effect of alteration of a single atom in the pendant unit was tried to be understood.

    (Pergamon-elsevier Science Ltd, 2009) Cihaner, Atilla; Mert, Olcay; Demir, Ayhan S.
    A novel conducting polymer was successfully synthesized via electropolymerization of 1-(1H-pyrrol-1-yl)-2,5-di(thiophen-2-yl)-1H-pyrrole. The electrochemical and electro-optical properties of the corresponding polymer, which was the first example of polymer containing 1,1'-bipyrrole units, were elaborated using electroanalytical and spectroscopic techniques. Cyclic voltammograms and electro-optical studies showed that the polymer has a stable and well-defined reversible redox process as well as electrochromic behavior. The processable polymer film also possessed a yellowish orange light emitter property. (C) 2008 Elsevier Ltd. All rights reserved.

    A New Conducting Polymer Bearing 4,4-difluoro-4-bora-3a,4a-diaza-<i>s</I>-indacene (bodipy) Subunit: Synthesis and Characterization
    (Pergamon-elsevier Science Ltd, 2008) Cihaner, Atilla; Algi, Fatih
    A new monomer system based on thiophene, pyrrole and 4,4-difluoro-4-bora-3a,4a-diaza-s-indacene dye (SNS-BODIPY) was synthesized and its corresponding polymer (PSNS-BODIPY) was obtained via repetitive cycling or constant potential electrolysis in 0.1 M tetrabutylammonium hexafluorophosphate dissolved in dichloromethane. The PSNS-BODIPY film has very stable and well-defined reversible redox couples during p-doping process. Multi-electrochromic polymer film has a band gap of 2.9 eV with two absorption bands in its neutral state at 351 and 525 nm, attributed to the polymer backbone and BODIPY subunits, respectively. The percentage transmittance changes between both states (neutral and oxidized) were found as 12.1% for 351 nm and 17.7% for 525 nm in the visible region as well as 46.2% for 1050 nm in the near-infrared region. Beyond the robustness, the PSNS-BODIPY film has high redox stability (retaining 53.3% of its electroactivity at 351 nm after 2000 switching) with a low response time of 1.0 s. (C) 2008 Elsevier Ltd.

    (2021) Balcı, Burcu; Cihaner, Atilla
    Lüminesan bileşikler, geniş uygulama alanları sebebiyle son zamanlarda büyük önem kazanmıştır. Ayrıca, kemilüminesan bileşikler, yüksek lüminesans hassasiyetlerinden dolayı analitik kimyada birçok çalışmada kullanılmıştır. Bu tezde elektron verici-alıcı-verici yaklaşımı ile, isimleri 5,8-di(furan-2-il)-2,3-dihidroftalazin-1,4-dion (F2B-Lum), 5,8-di(selenofen-2-il)-2,3- dihidroftalazin-1,4-dion (S2B-Lum) ve 5,7-di(selenofen-2-il)-2,3-dihidrotiyeno[3,4-d] piridazin-1,4-dion (S2T-Lum) olan, yeni bir kemilüminesan bileşik serisi sentezlenmiştir. Yapıları NMR, FTIR ve HRMS teknikleri kullanılarak doğrulanmıştır. Daha sonra, alkali çözeltide (0,1 M NaOH(sulu)) bileşiklerin hidrojen peroksit ile farklı metal iyonları, hemin ve kan örnekleri varlığında kemilüminesans tepkimeleri araştırılmış ve sonuçlar luminol ile karşılaştırılmıştır. Beklendiği gibi, bileşiklerin bakır(II), demir(III) iyonlarına ve kana duyarlı olduğu gözlenmiştir. Yeni luminol türevleri olarak ilgili bileşiklerin, adli bilimde kan bulgularının tespiti için potansiyel adaylar olduğu sonucuna kolaylıkla varılabilir. Ek olarak, bileşiklerin bakır(II) iyonuna duyarlılığı, onları analitik uygulamalarda bakır iyonu tanıma için kullanılabilir hale getirmiştir. Ayrıca, bileşiklerin redoks davranışlarını araştırmak için döngülü voltametri tekniği kullanılmış ve tersinmez yükseltgenme sinyalleri göstermişlerdir. Ayrıca bu bileşikler kullanılarak -1.05 V'luk bir dış potansiyel uygulanarak kare dalga potansiyel yöntemi ile reaktif oksijen türleri tespit edilebilmektedir.Son olarak bileşiklerden S2T-Lum elektrokimyasal olarak başarılı bir şekilde polimerleştirilmiştir. İlgili polimer PS2T-Lum, elektroaktif olduğu ve polimerik yapısında kemilüminesan aktif uzantılar taşıdığı için luminol tipi polimerlerin değerli bir üyesi olabilir.

    Catalyst-Free Synthesis of Thiourea-Linked Dumbbell-Shaped POSS for Ultrasensitive Determination of Prilocaine in Human Blood With Computational Insights
    (Elsevier, 2026) Bilge, Selva; Bayraktar, Ece Nur; Erkmen, Cem; Balci, Burcu; Abofoul, Anas; Ozkut, Merve Icli; Cihaner, Atilla
    Although various electrochemical sensors have been reported for the determination of local anesthetic drugs, most existing platforms suffer from limited sensitivity, insufficient surface stability, or inadequate electron-transfer efficiency, particularly when applied to complex biological matrices. Moreover, the potential of hybrid polyhedral oligomeric silsesquioxane (POSS)-based nanostructures combined with metal oxide nano-particles for improving electroanalytical performance has not yet been thoroughly explored. In this study, a high-sensitivity electrochemical nanosensor was developed for the determination of prilocaine (PC), an amide-type local anesthetic, using a glassy carbon (GC) electrode modified with POSS-titanium dioxide (TiO2) nano-particles (Nps). The combination of modifications provided a unique electrode surface by combining the high stability of POSS with the strong adsorption properties of TiO2 Nps, thereby increasing both surface loading and adsorption capacity. To elucidate the structure of the modification combination, 1H and 13C nuclear magnetic resonance (NMR) and Fourier transform infrared (FTIR) spectroscopic techniques, as well as Brunauer-Emmett-Teller (BET), X-Ray diffraction (XRD), Electrochemical impedance spectroscopy (EIS), and high-resolution transmission electron microscopy (HRTEM) analysis techniques were used, respectively. The analytical performance of the developed nanosensor was systematically optimized using differential pulse voltammetry (DPV), adsorptive stripping differential pulse voltammetry (AdSDPV), square wave voltammetry (SWV), and adsorptive stripping square wave voltammetry (AdSSWV) techniques. As a result of the optimization studies, the lowest limit of detection (LOD) was 3.66 x 10-8 M with the AdSSWV technique. DFT results corroborated the mechanism, indicating ring-centered electron donation (HOMO) and adsorption-favored N/O regions (MEP). Low LOD values were also recorded with other techniques, demonstrating the method's high sensitivity in analyte detection. In real sample analysis tests, PC recovery value in human blood samples was determined to be 98.69% using the AdSDPV technique. Despite the matrix effect, the nanosensor demonstrated high accuracy and reproducibility. The results indicate that the developed POSS-TiO2 Nps modified GC electrode sensor offers a high-performance, reliable, and good electrochemical detection platform suitable for use in biological and clinical applications.

    Pyrrole Coupling Chemistry: Investigation of Electroanalytic, Spectroscopic and Thermal Properties of N-Substituted Poly(bis-Pyrrole) Films
    (Royal Soc Chemistry, 2013) Mert, Olcay; Demir, Ayhan S.; Cihaner, Atilla
    An etheric member of N-linked polybispyrroles (PolybisPy) based on 1-(3-(2-(2-(3-(1H-pyrrol-1-yl)propoxy)ethoxy)ethoxy)propyl)-1H-pyrrole (1) was electrochemically synthesized for the versatile investigation of its exciting electrochromic and ion receptor properties. It has been fully characterized by electroanalytic, spectroscopic, thermal, and four-probe techniques. It was thereby found that P1 shows strong stability, and a reversible redox process as well as a good electrochromic material property; transparent yellow in the neutral state, light pink in the intermediate state, and blue in the oxidized state. Also, the corresponding polymer (P1) exhibited a selective voltammetric response towards Na+ among the alkali series in an organic medium. Moreover, P1 film was employed for the detection of Ag+ ions in the solution with cyclic voltammetry without precipitants or complexing ligands, and SEM images confirmed the deposition of metallic silver on the film surface. These prominent features also make P1 a good candidate for many practical uses, such as the recovery of metals and ion sensors.

    Kan İzlerinin Tespiti: Luminol-türü Bir Bileşik Sentezi ve Karakterizasyonu
    (2021) Kesimal, Büşra; Cihaner, Atilla
    Luminol başta adli-tıp olmak üzere analitik ölçümler dâhil birçok alanda kullanılan bir bileşiktir. Luminolün birçok alanda kullanılması ve bazı dezavantajlara sahip olması nedeniyle yeni luminol-tipi bileşiklerin sentezlenmesi büyük önem kazanmıştır. Bu tezde piridazin halkası içeren trimerik kemilüminesans 5,8-di(tiyofen-2-il)-2,3-dihidroftalazin-1,4-dion (T2B-Lum) bileşiği üzerinde çalışılmıştır. Sentez ve karakterizasyondan sonra, bileşiğin kemilüminesans tepkimeleri bazik ortamda (0,1 M sodium hidroksit çözeltisinde) farklı yükseltgenler (hidrojen peroksit, potasyum permanganat, potasyum dikromat) ile incelenmiştir. Sonrasında, T2B-Lum'un optiksel özelliği ve hidrojen peroksit ile beraber alkali ortamda farklı metal iyonlarının varlığında kemilüminesans tepkimesi çalışılmıştır. T2B-Lum'un diklorometan içerisinde 262 ve 330 nm'de iki soğurma bandı olup uyarıldığında 495 nm'de yeşil ışık yayar. Luminolün kuantum verimi %100 olarak alındığında diklorometan içerisinde T2B-Lum'un kuantum verimi %15,11 olarak hesaplanmıştır. Diğer bir taraftan, bazı metal katyonlarının, özellikle bakır(II) iyonlarının, kemilüminesans tepkimeyi katalizlediği gözlenmiştir. Ayrıca kemilüminesans ışımanın demir(III) iyonu ile katalizlendiği gözlenmiştir. Bu gözlemden sonra alkali çözeltide T2B-Lum'un hidrojen peroksit ile kemilüminesans davranımları katalizör olarak kullanılan hemin ve kan örneklerinin varlığında çalışılmıştır çünkü bu örnekler demir iyonları içermektedir. Son olarak T2B-Lum'un iyon tanıma özelliği incelenmiştir. Diğer metal katyonları (gümüş(I), kadmiyum(II), kobalt(II), demir(III), lityum(I), magnezyum(II), manganez(II), nikel(II), çinko(II)) dışında, T2B-Lum'un 2.2×10-3 M'lık bir saptama sınır değeriyle bakır iyonuna duyarlı olduğu gözlenmiştir.

    Electroinitiated Polymerization of 2-Allylphenol
    (Springer-verlag, 2000) Cihaner, A; Önal, AM
    Redox behaviour of 2-allylphenol (2APhOH) was studied by using cyclic voltammetry (CV) and electroinitiated polymerization was conducted at the measured peak potentials. Constant potential electrolysis (CPE) of the monomer was carried out in acetonitrile-sodium perchlorate, solvent-electrolyte couple, at room temperature. Polymerization of the monomer yielded insoluble polymer films on the surface of the electrode together with the low molecular weight polymers in the bulk of the solution. The structural analysis of the polymers were carried by H-1-NMR and FTIR spectroscopy. Molecular weight of the soluble polymer was determined by GPC. Thermal properties of the polymer film and soluble polymer were studied by DSC. The course of electroinitiated polymerization was monitored by in-situ UV-VIS spectroscopy.

    Impedance Spectroscopy of N-Substituted Oligo-Oxyethylene Polypyrrole Films
    (John Wiley & Sons inc, 2008) Cihaner, Atilla; Onal, Ahmet M.
    The electrochemical properties of neutral (dedoped) and oxidized (doped) poly(1,11-bis(1,1-pyrrole)-3,6,9-trioxaundecane) (poly-I) film electrodes were investigated using cyclic voltammetry and electrochemical impedance spectroscopy (EIS) techniques. Poly-I was deposited on glassy carbon electrode (GCE) from acetonitrile solution containing 5.0 x 10(-3) M 1,11-bis(1,1-pyrrole)-3,6,9-trioxaundecane (I) and 0.1 M LiClO4 supporting electrolyte. Doped poly-I exhibits a single semicircle in its complex-capacitance plots, indicating a single dominant ion transport process, together with high capacitance values. These features make this polymer film a candidate for an energy storage material. Also, poly-I can be a candidate as a sensory material for the detection of Ag+ based on impedance parameters.

    From Narrow To Narrower: a Very Low Band Gap [1,2,5]thiadiazolo[3,4-G]quinoxaline Donor-Acceptor Type Electrochromic Polymer
    (Electrochemical Soc inc, 2017) Gokce, Gurcan; Karabay, Baris; Cihaner, Atilla; Ozkut, Merve Icli
    The development of low bandgap polymers (or zero bandgap polymers) is still one of the main goals of scientists and many viable paths have been formulated in order to accomplish this. In this study, a donor-acceptor-donor type electrochromic polymer based on [1,2,5]thiadiazolo[3,4-g]quinoxaline acceptor and selenophene donor units with extremely low bandgap (ranging from 0.21 to 0.60 eV depending on bandgap determination method) is synthesized and characterized electrochemically, optically and colorimetrically. Electrochemical and optical studies showed that the polymer film was susceptible to both n- and p-type doping and has a mustard color in its neutral state, and upon oxidation its color changed to brown, and upon reduction the color is light purple.
