AFM study of photostimulated structural changes of liquid crystal surfaces

The surface morphology and optical properties of liquid crystal films doped with photochromic dithienylethene compounds are shown to be reversibly altered by photoirradiation. The photo- switching between two optical and structural states is based on the photochromism of the dithienylethene dopant which may exist as an open or as a closed isomer. While the open isomer has a twisted structure and exhibits an absorption spectrum in the uv, the absorption
