Composite quasi-crystalline material

摘要

A composite quasi-crystalline material made of a polymeric support matrix having disposed therein polar quasi-crystals of photochromic spiropyran complexes, believed to be of the formula AnB, in which A represents the "colorless" photochromic spiropyran molecule and B represents the colored merocyanine form which is the photolysis product of A, and n is 2 or 3. The polar quasi-crystals are present in the composite material in a substantially polar aligned form. Methods for making the composite material are also disclosed.
