Synthesis and Charge Transport Properties of Polymers Derived from Oxidation of 1-H-1'(6-pyrrol-1-yl)-hexyl-4,4'-bipyridinium
Abstract
This article describes the synthesis and electrochemical properties of redox polymers, having a poly-pyrrole backbone and viologen subunits, derived from oxidative electropolymerization of 1-methyl-1-1'-(6-pyrrol-1-yl)-hexyl-4, 4'-bipyridinium, (P-V-Me2+), and 1-H-1'-(6-pyrrol-1-yl)-hexyl-4,4'-bipyridinium, (P-V-H2+). Closely spaced (approx. 1.5 micro m) Au microelectrode arrays (approx. 2.5 micro m) wide x 50 micro m long x 0.1 micro m high) modified with the polymers can be used to study aspects of the charge transport behavior of the viologen redox system. Poly(P-V-Me2+) and poly(P-V-H2+) have been used to investigate the characteristics of microelectrochemical transistors based on a viologen redox center, and a similar redox center, protonated, mono-quanternized bipyridinium, which is pH dependent.
