摘要：
A new series of 2,5-bis(arylethenyl)siloles la-d was prepared by the reaction of the corresponding zirconacyclopentadienes with H2SiCl2 in CH2Cl2. Absorption maxima of siloles la-d were observed in the significantly longer wavelength region compared to those of distyryl-substituted benzenes and heteroles. The emission spectrum of distyrylsilole la showed a large Stokes shift compared with distyrylsilole 2.
