Title: Clustering Effects In Polyaniline Chains

Abstract: Theoretical investigations on the effect of random protonation on the electronic behaviour of long finite chains of polyaniline have shown that the presence of disorder is an essential feature to explain the observed semiconductor-metal transition. In this work we have extended the study of disorder including a pair correlation (short range order) parameter in order to simulate the effects of segregation (clustering) in one-dimensional chains. Our results have shown that the inclusion of these aspects do not affect the general features earlier obtained, disorder is still in the origin of the semiconductor-metal transition. © 1993.
