Abstract
Dichloromethyl(2,9-diphenyl-7,8-benzophenanthryl)silane (1) was synthesized by the Diels–Alder reactions of dichloromethylvinylsilane with 2,5-diphenyl-3,4-(o,o′-biphenylene)cyclopentadienone in a sealed tube. Poly [methylphenylsilylene-co-(2,9-diphenyl-7,8-benzophenanthryl)methylsilylene] (PMBSI) was obtained by Wurtz-type coupling of dichloromethylphenylsilane and 1 and was characterized with Fourier transform infrared, 1H-NMR, 13C-NMR, 29Si-NMR, gel permeation chromatography, and ultraviolet and fluorescence spectroscopy. The conducting properties and thermal properties of the polymer were investigated. Because of the introduction of benzophenanthrene groups into the Si atoms of the polymer, the ultraviolet absorption wavelengths of the PMBSI redshifted significantly in the ultraviolet region, and a strong photoluminescence band could be observed in the visible region. © 2007 Wiley Periodicals, Inc.
