摘要：

A new pi-conjugated organometallic polymer of which framework is in part composed of cobaltacyclopentadienes has been synthesized by a metallacycle formation reaction of CpCo(PPh3)2 with 4,4'-diethynylbiphenyl. The polymer, poly(4,4'-biphenylene 2,5-cobaltacyclopenta-2,4-dienylene) has a strong absorption band around 500 nm, and is oxidized at +0.306 V vs. Ag/Ag+ in dichloromethane and reduced at -1.8 V in acetonitrile.
