Abstract

We have presented polarized photoluminescence (PL) from photopatterned discotic liquid crystal (DLC) film. Photopatterned DLC film was accomplished by the photoalignment technique consisting of oblique photoirradiation with non-polarized light and the subsequent annealing of an azobenzene-containing polymer thin film. The DLC molecules were aligned in a tilted hybrid manner as a result of the inclined orientation of the azobenzene moieties. Micro-patterned PL was observable by imagewise nonpolarized excitation of the photoaligned DLC film.
