Abstract
Copolymerization of 3-(4'-butyl-4'-methyl-4'-silaoctyl)thiophene with 3-nonylthiophene was carried out and the effects of photooxidation on the electrical properties of the resulting copolymer (I) were compared with those of poly(3-nonylthiophene-2,5-diyl) (PNT). Photooxidation o f both PNT and I shifted the lambda(max) to shorter wavelengths due to conjugation-breaking reactions. The extent of the conjugation-breakin g reactions by photooxidation was higher in I than in PNT for a given exposure. Films of I were undopable after irradiation.
