SYNTHESIS AND ELECTROCHEMICAL PROPERTIES OF A POLYNORBORNENE DERIVATIVE CONTAINING A CARBAZOLE MOIETY

Abstract

A new Polymer, Poly{5-[[(6-N-carbazoylhexyl)oxy]methyl]-2-norbornene} [Poly(NCHN)], was synthesized by ring-opening metathesis polymerization(ROMP) with various transition metal catalyst systems. The structure of the poly(NCHN) was analyzed by NMR, IR, and UV-vis spectroscopy. The electrochemical properties of the poly(NCHN) were characterized by cyclic voltammetric technique. From the cyclic voltammetric results it was concluded that the carbazole units in side chain of the polymer were oxidized and coupled irreversibly to form dicarbazyls. The redox kinetics was mainly controlled by both electron transfer and ClO4- diffusion processes preserving the electro-neutrality of the polymer.
