Abstract
Optical buffing of alignment Jayers1 for liquid crystals device applications has generated a considerable interest recently. To make efficient use of optical alignment, detailed understanding of photoinduced orientation of azo-dye molecules in the alignment layer and the coupling between the dye and the bulk liquid crystal is necessary. A simple model for the latter has already been proposed,2 In this paper we study the time evolution of photoinduced anisotropy in azo-dye doped polyimide films. The orientational kinetics of chromophores in polymers is also of interest to the χ(2) materials community.
