摘要

Regioregular organometallic polymers possessing titanacyclopentadiene-2,5-diyl units in the main chain were converted into new π-conjugated polymers possessing various elements-blocks such as thiophene-1-oxide, selenophene, tellurophene, phosphole, stibole and bismole. Subsequent chemical modifications of the polymers possessing 1,4-bismericapto-1,3-diene, tellurophene, and phosphole units were also carried out to give π-conjugated polymers that exhibit unique optoelectronic properties. Namely, the polymers obtained in the present studies exhibited both p-type and n-type semiconducting properties depending on the nature of the elements-blocks attached to the π-electronic systems. The narrow band gap materials have also been prepared by the facile molecular design of diynes. For example, a phosphole-containing polymer obtained from diethynyldithienogermole was subjected to the chemical modifications at its phosphorus atom to obtain polymers with band gap (E_g) less than 1.3 eV. Some of the polymers were found to be potentially applicable to photovoltaic cells.
