• Infrared spectroscopy on the reorientational and phase transitional behavior of a liquid crystal photo-regulated by 'Command Surfaces'

抄録

Phase transitional and reorientational behavior of a nematic liquid crystal photo-regulated by azobenzene derivative Langumuir-Blodgett (LB) film or 'Command Surfaces' have been studied by infrared spectroscopy. A thermal isomerization from cis to trans conformations takes place within 15 minutes from the completion of ultraviolet irradiation, while a consequential phase transition from homeotropic to isotropic phases has been found about three quarters of an hour after the irradiation. FT-IR thus is very powerful technique to determine of the phase transition between homeotropic and isotropic as well as the reorientation.
