Abstract

Conjugated polymers containing sterically protected 1,2-di(2-thienyl)-3,4- diphosphinidenecyclobutene units were prepared and their properties were investigated. Red shifts of the polymers were observed, compared to the corresponding monomeric species, which indicates extension of the π system on polymerization.
