Poly(methacrylate) copolymer containing 95 mol% of photoreactive H-bonded mesogenic unit 4-(6-hydroxyhexyloxy) cinnamic acid (6CA) and 5 mol% of luminescent unit 2,7-bis[2-(4-hydroxyphenyl)-2-cyanovinyl]-9,9-dihexyl-9H-fluorene (CN-DHFP) was synthesized and characterized. The irradiation with LPUV light resulted in the induction of a small negative optical anisotropy (DA) in the films due to the axis selective photoreaction of the cinnamic acid group. After annealing, the negative optical anisotropies both 6CA and CN-DHFP groups were significantly enhanced. The enhanced reorientation direction of both groups was perpendicular to E of LPUV light. Polarized blue emission was obtained with polarization ratio of about 2.0.
