Thin film optical medium of a multiple amphiphilic bilayer composite |
摘要 |
This invention provides novel self-assembled multilayer organic thin films including an azo-benzene chromophore which initially appear substantially amorphous when viewed perpendicular to the film surface, but are subsequently treated with a laser in selected areas so that such portions exhibit photo-induced birefringence.
