Abstract
The first observation of alignment of a liquid crystal deposited on a poly[ methyl(phenyl)silylene] (PMPSi) film irradiated with linearly polarized lig ht is reported. The effect seems to be controlled by the angular-dependent photodegradation caused by the photoinduced scission of the Si-Si bonds in the polymer backbone connected with the: formation of other photoproducts p referentially oriented along the light polarization.
