摘要: 本文合成了一种新型的两亲性酞菁分子,研究了它在不同溶剂中的聚集行为,考察了酞菁及酞菁与正十六烷混合的成膜性能,制备了混合的多层LB膜,并利用紫外光谱研究LB膜内的分子聚集状况,用分子激子理论对实验结果加以分析,还应用偏振紫外的方法对LB膜内酞菁分子大环的取向进行了确定。

Abstract: A novel amphiphilic zinc phthalocyanine(TAZnPc)was syntesized.Its behavior toward aggregation in different solvents was studied.Monolayers of pure TAZnPc and a 1:10 mixture of TAZnPc with 1-hexadecane were spread on water from ether solution andtransferred onto CaF2 slides. It is indicated that the mixed LB film is more stable than theLB film of pure TAZnPc. Multilayers were also built up on these substrates. Polarized UVabsorption spectra of the mixed LB films together with the molecule area in condensed mixedmonolayer lead to the conclusion that the phthalocyanine macroring is lying nearly parallel tothe substrate surface.

Key words: phthalocyanine, aggregation, LB film, molecule exciton, measurementmethod of polarized ultraviolet absorption spectrum
