利用经典静电场理论,描述了Y型Langmuir-Blodgett(LB)膜中棒状分子聚集行为的偶极作用模型,给出了Y型LB膜结构与光谱性质的关系.讨论了Y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,并在此基础上比较了Y型膜和Z型膜分子聚集行为的异同.理论结果与实验规律符合较好.
Based on the classical electrostatic field theory, the dipole action model of the rod-shaped molecular aggregation in the Y-type Langmuir-Blodgett (LB) film is described and the relationship between the structure and the spectral properties of the Y-type LB film is given. , The influence of structural parameters such as layer orientation, molecular orientation and film number on the molecular aggregation behavior were discussed. The similarities and differences of the molecular aggregation behavior of Y-type and Z-type membranes were also compared. The theoretical results agree well with the experimental data.
