研究了偶氮苯衍生物掺杂的聚（L-谷氨酸γ-苄酯-co-L-谷氨酸γ-十二烷基酯）。通过改变薄膜的螺距和十二烷基含量，探索了诱导圆二色性（ICD）强度的最佳条件。通过改变薄膜的退火温度来改变薄膜的间距。当x=0.63的聚合物在180°C下退火时观察到最强的ICD（螺距= 6.7 μm）。将ICd强度与反螺距曲线图与基于Eschrasekhar理论计算的理论曲线进行比较
Poly(γ-benzyl L-glutamate-co-γ-dodecyl L-glutamate) doped with an azobenzene derivative was studied. Optimum conditions for the induced circular dichroism (ICD) intensity were explored by varying the cholesteric pitch of the film and the content of the dodecyl groups x. The cholesteric pitch was varied by changing the annealing temperature of the film. The strongest ICD was observed when the polymer with x=0.63 was annealed at 180°C (cholesteric pitch= 6.7 μm). The ICd intensity vs inverse pitch plot was compared with theoretical curves calculated on the basis of Chandrasekhar's theory
