Electrochrometic measurements were carried on the Z-type Langmuir-Blodgett films of two liquid crystalline polymers: mono-{6-[4-(phenylazo) naphthyloxy] hexyl} (1a) and mono-{6-[4-(anthraquinone-1-azo) naphthyloxy] hexyl} (2a) ester of polymaleic acid. It was found that for both polymers, poling fields parallel and antiparallel to dipole moments of the polymer side chains induce red and blue shift in absorption bands, respectively. For polymer 1a blue shift is accompanied by absorbance increase, while red shift by absorbance decrease;but for polymer 2a only decrease in absorbance is observed. A simple model was proposed to analyze the results. 展开更多
