Abstract

For the multifunctional liquid crystalline medium with high chromophore content, a thermotropic polymethacrylate (PBBS) bearing monolithic photoactive mesogen was designed and synthesized on the basis of semiempirical quantum calculation. PBBS showed phase transition sequence of I-222 °C-SmA-169 °C-SMC-154 °C-SmX on cooling. Phase transition in the PBBS film could be correlated with the birefringence change and H-aggregate formation monitored as a function of temperature. The multifunctional mesogenic pendant, 2-biphenyl-5-sulfonylbenzoxazole, provided strong blue fluorescence and electroluminescence, large second-order optical nonlinearity, and intrinsic photeconductivity to the novel photoactive liquid crystalline polymer PBBS.
