Infrared photoinduced change of liquid crystal domains was investigated for a hexagonal columnar mesophase of a triphenylene derivative. A uniform change of domains was observed when an infrared laser beam corresponding to the wavelength range with the absorption band of triphenylene core was irradiated. The texture change means that a change of the molecular alignment occurred and it seems that the direction of columnar axis depends on the direction of the incident laser beam. It could provide a novel technology to control the alignment of liquid crystals with high viscosity.
