摘要：

An infrared technique for molecular alignment control of discotic columnar liquid crystals is described. The liquid crystal domain change was induced in hexagonal columnar mesophase by infrared irradiation with a vibrational excitation of the chemical bonds in the triphenylene mesogen. In the new domain a uniform alignment of molecules was attained and the behaviour is essentially related to the polarisation of the incident beam. Also the new domain is quite stable, though depending on temperature. However, such a new domain formation was not observed in the discotic nematic phase.
