摘要：

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 nonpolarized 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. Micropatterned PL was observable by imagewise nonpolarized excitation of the photoaligned DLC film.
