MODIFYING THE ELECTROCHROMIC PROPERTIES OF SOME NOVEL NON-CONJUGATED POLYMERS WITH PENDANT TERARYL GROUPS

摘要

A series of N-substituted-2-(5'-vinyl-2'-thienyl)-5-(2''-thienyl)pyrroles were synthesized and their electrochromic properties studied. In an attempt to tailor the observed color, copolymers of 5-vinylterthiophene and N-phenyl-2-(5'-vinyl-2'-thienyl)-5-(2''-thienyl)pyrrole were prepared using different stoichiometries. In another approach we synthesized copolymers of (i) N-vinylcarbazole and 5-vinylterthiophene and (ii) N-vinylcarbazole and N-phenyl-2-(5'-vinyl-2'-thienyl)-5-(2''-thienyl)pyrrole. [References: 6]
