Preparation and Property of Polytellurophene and Polyselenophene

Abstract
Polytellurophene is prepared chemically using FeCl3 as catalyst at the first time. The electrical conductivity in the doped state is found to be relatively low, 10-6 S/cm, compared with that in polythiophene. Polyselenophene films prepared by a chemical method are found to indicate similar characteristics with those of electrochemically prepared films.
