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 theory of electrostatic field, the dipole action model of rod-shaped molecular aggregation in Langmuir-Blodgett (LB) film is described and the relationship between the structure and the spectral properties of LB film is given. The relationship between molecular spacing and interlayer spacing , Molecular orientation, film number and other structural parameters on molecular aggregation behavior.The theoretical results agree well with the experimental values.
