Abstract

Combinative dechloro/dehydro catenation of 1,1-dichlorotetraphenylsilole 1 with < 150 mol% of various inorganic hydrides in THF at 25°C produces optoelectronic polysiloles 2 in high yield. Similarly, cocatenation of 1 and 1,1-dichlorotetraphenylgermole 4 (9:1 mole ratio) using 110 mol% of Red-Al in THF at 25°C gives poly(silole-co-germole) 5 in high yield. The polymers emit green light at 520nm and are strongly electroluminescent at 520nm.
