利用红外透射光谱、偏振透射光谱、掠角反射光谱研究了三－２，４－二特戊基苯氧基８－喹啉氧基酞菁铜ＬＢ膜和蒸镀膜的结构。确认在ＬＢ膜中，（１）取代基的碳链是以六方晶系或假六方晶系方式堆积的；（２）用偏振红外可以区别苯环上的两个ＣＨ２的伸缩振动带。在蒸镀膜中分子基本呈现无序状态 The structure of LB films and deposited films of tris-2,4-di-t-pentylphenoxy-8-quinolyloxyphthalocyanine was studied by infrared transmission spectrum, polarized transmission spectrum and sweep angle reflection spectrum. It is confirmed that in the LB film, (1) the carbon chains of the substituents are stacked in a hexagonal system or a pseudo-hexagonal system; (2) the polarization bands of two CH2 on the benzene ring can be distinguished by the polarization infrared. In the vapor deposited film, the molecules are basically disordered
