Abstract

Abstract Factors which could influence the energy gap ΔE of an organic semiconducting polymer have been investigated by a study of the electrical conductivity of some nitrogen heterocyclic polymers, in particular paracyanogen, macrocyclic polymers and poly[benzobis(aminoiminopyrrolenines)]. The electrical behaviour of paracyanogen is similar to that of the related polyacene suggesting that the energy gap ΔE is not appreciably affected by replacement of methine groups by nitrogen in the polymer. The macrocyclic polymers have larger ΔE than the polypyrrolenines and for each series the energy gaps of the polymers derived from 4,4′-diaminodiphenyl ether and paraphenylene diamine are comparable, whilst the metaphenylene diamine is lower.
