Аннотация

A new series of 2,5-bis(arylethenyl)siloles 1a–d was prepared by the reaction of the corresponding zirconacyclopentadienes with H2SiCl2 in CH2Cl2. Absorption maxima of siloles 1a–d were observed in the significantly longer wavelength region compared to those of distyryl-substituted benzenes and heteroles. The emission spectrum of distyrylsilole 1a showed large Stokes shift compared with distyrylsilole 2.
