Abstract

Free volume in polymer matrices has been revealed with a photo-reactive probe technique by using various photochromic compounds and polymer matrices. The effect of photoreactions of diarylethene derivatives in methyl methacrylate polymer was determined in terms of inhomogeneous distribution of solid state photochromic reaction. The quantum yield of the photoisomerization from open-ring isomer to close-ring one, and the backward reaction were determined by the change in absorption during isomerization. The forward reaction is inhomogeneous due to conformational distribution of diarylethene.
