摘要
基于经典静电场理论,描述了Langmuir_Blodgett(LB)膜中棒状分子聚集行为的偶极作用模型,给出了LB膜结构与光谱性质的关系.讨论了X型或Z型膜中分子间距、层间距、分子取向、膜层数等结构参数对分子聚集行为的影响.理论结果与实验值符合较好.
Based on the classical electrostatics theory, the model of dipole-dipole interaction in the aggregation of rod-like amphiphilic molecules in Langmuir-Blodgett（ LB）films has been presented in the paper. The relations between LB films structure and spectral absorption peak were obtained by using this model. For Z-type films, the dependence of molecular aggregation state on the structure parameters, i.e. separation distance α, separation between two adjacent layers d, molecular orientation θ, and layer number g, were studied by applying our model. The theoretical results agree well with experimental data.
