摘要

An optically aligned polymer with linearly polarized light is used to align uniaxially a liquid crystalline fluorescent polymer, poly(9,9-dioctylfluorene) (PFO). The optically aligned polymer has negligible absorption for visible light regime and is stable at relatively high temperature in air. The aligned PFO film shows the significant dichroic ratios in absorption and photoluminescence. The photoconductivity is sensitive to the polarization of the excitation light.
