sigma.,.pi. Charge-transfer excited states of substituted (phenylethynyl)pentamethyldisilanes

A series of substituted (arylethynyl)pentamethyldisilanes was prepared by the palladium(O)-catalyzed coupling of aryl halides and ethynylpentamethyldisilane. The absorption and emission spectra of these acetylenic disinaes were measured over the temperature range from 296 to 77 K in both polar and n...
