A novel class of polymers comprises one or more dipyridinium units, having the formula ##STR1## contained within the main polymer backbone where Ar.sup.1, Ar.sup.2, and Ar.sup.3 are aromatic or heteroaromatic nuclei each of which can consist of one ring or two fused or catenated rings having 5 to 12 ring carbon and heteroatoms which can include 1 to 3 unitary heteroatoms selected from S, N, and O, R.sup.1 is any divalent organic bridging group, and Z.sup..crclbar. is a counterion.
一种新型聚合物类别包括一个或多个二
