摘要
The optical properties and the formation of charged species of a newly synthetized soluble thiophene/phenylene block copolymer are studied with Raman scattering, optical and photoinduced absorption spectroscopies. The optical properties of the copolymer are determined by its low-gap segments, strictly resembling the dialdehyde sexithiophene molecule. Charged species, injected by chemical doping and by photoexcitation, are polarons which accommodate within the thiophene blocks of the copolymer. (C) 1998 Elsevier Science S.A. All rights reserved.
