Abstract in another language

Polyesters with substituted bis(styryl)benzene segments, biphenylene segments, and linear aliphatic spacers in the main chain were obtained by polycondensation. These polyesters show intensive photoluminescence and exhibit thermotropic behavior. UV dichroism, polarized photoluminescene, and polarized electroluminescence were observed when films of the polyesters were cast from solution on rubbed polyimide and subsequently annealed. LC phases get disorders with increasing amount of biphenylene moieties in the main chain. The macroscopic order parameters derived thereof are a nonlinear function of the order of the LC-phase.
