Abstract

Electropolymerizable monomers of the formulas

wherein R₁, R₂ and R₃ are selected from the group consisting of —H, —O(CH₂)_nCH₃,

wherein n has a value of 0 to 11 and m has a value of 1 to 4, and wherein no more than one of R₂ and R₃ is —H. Also provided are polymers resulting from the electropolymerization of these monomers.
