Outline of Final Research Achievements

Photochemical and electrochemical ring-closing reactions of poly(arylene-vinylene) derivatives possessing tetra-aryl ethylene units were performed to obtain π-conjugated polymers possessing extendedπ-electron systems. Under the examined conditions, the objective annulation occurred smoothly to give the products that exhibit entirely different luminescent properties. The model annulation reactions using 2,3-di(2-thienyl)stilbene were likewise performed to evaluate the possibility to obtain heteroatom-doped graphene nanoribbons. The benzodithiophene derivatives produced by the model experiments were subjected to the electrochemical polymerization to giveπ-conjugated polymer thin films that exhibit electrochromic properties.
