摘要：

Poly[2,5-(tetramethyldisilanylene)thienylene] (Ib), poly[2,5-(1,2-dimethyldiphenyldisilanylene)thienylene] (IIb) and poly(2,5-[1,2-di-methyldi(p-tolyl)disilanylene]thienylene} (IIIb) were synthesized by sodium condensation reaction of the corresponding 2,5-bis(chlorosilyl)thienylenes in decane. Polymers Ib-IIIb reveal characteristic absorptions in the UV region. Irradiation of the thin films of Ib-IIIb in air led to disappearance of these absorptions. The photolysis of Ib-IIIb in a benzene solution resulted in homolytic scission of silicon-silicon bonds in the polymer backbone. In the photolysis of Ib, the cross-linking reaction occurred, while polymers IIb and IIIb afforded photodegradation products with low molecular weights.
