Abstract

A photochromic diarylethene was found to crystallize rapidly from the amorphous state in poly(methyl methacrylate) by heating at 130 °C. The diarylethene amorphous film was successfully patterned to form microcrystals upon ultraviolet (UV) light irradiation through a photomask, showing a high resolution as good as ∼4 μm under optimal conditions.
