Design, Synthesis, Properties and Applications of Novel Processable Luminescent and Redox Active Compounds

Luminescence is the emission of electromagnetic radiation (in ultraviolet (UV), visible (Vis) or infrared (IR) regions) with no or little heat, which is produced by the transition of an electronically excited state intermediate generated by the application of an external stimuli to a lower (ground) state in order to release the excess energy. If the electronically excited state returns to the ground state from the lowest singlet excited state, it is called fluorescence or if it returns from the triplet excited state, it is called phosphorescence. The light emitted may be in UV and Vis regions as well as in IR region. Luminescent compounds have recently attracted considerable attention due to their practical applications in bio- and nanotechnological as well as materials sciences as chemosensors, electron and/or energy transfer systems, imaging agents, molecular machines and devices, molecular logic gates and so on. For that reason, the design, synthesis and characterization of novel luminescent compounds are highly concerned by first the synthetic organic chemists and as well as other communities all around the world. Herein, luminescent and redox active novel compounds (1-3) were designed, synthesized and characterized spectroscopically (UV-Vis, luminescence-fluorescence, FTIR, NMR, mass spectroscopy, combustion analysis, cyclic voltammetry). Furthermore, some applications of these novel compounds in analytical and/or material science (e.g. in forensic science, chemosensors) were investigated. In the last step of the work, these novel compounds were polymerized to give the corresponding polymeric materials, which were also characterized by spectroscopic methods.
