Abstract

The photoisomerization of azo dyes in liquid crystalline hosts was studied. It was shown that the parameters governing the isomerization process could be found from the polarized pump-probe transmission measurements. It was found that the dye order parameter for the trans isomer was relatively high and was strongly related to the liquid-crystalline order. The cis isomer showed a much lower dye order parameter and was not strongly dependent on the liquid-crystalline phase.
