Synthesis of new type of conducting polymers containing side groups their electrochemical and photochemical characterizations

In this thesis, electroactive monomer containing acceptor side groups was synthesized and polymerized onto the surface of ITO/glass via electrochemical process. Structural characterizations of all synthesized compounds were identified by using FT-IR and 1H-NMR spectroscopy. The optical and electrochemical HOMO-LUMO band gap values were calculated by using UV-Vis absorbtion and cyclic voltametry (CV) measurements, respectively. In addition, electron-energy transfer mechanisms of synthesized donor-acceptor structures were determined by utilizing UV-fluorescence, UV-Vis and cyclic voltammetry measurements. Electrochromic behaviours of donor-acceptor polymers coated on to ITO/glass surface via electrochemical process were determined by the spectro-electrochemical measurements. It was possible to observe a wide color scale on the same polymer film with different potentials. As a result of kinetic study, oxidation and reduction response times and stabilities of the polymer films were determined as quite good.
