摘　　要：本文报导了一种新型的两亲性分子——长链对称取代锌酞菁（ＴＡＺｎＰｃ）ＬＢ膜的制备和结构特点。研究了其固相和ＬＢ膜的红外光谱。用偏振—付立叶变换红外光谱研究了ＬＢ膜内长脂肪链的取向。结果表明该分子具有良好的成膜性能，分子环平面基本上与基片相平行，而长脂肪链由于链密度很稀，采取倾斜取向。Abstract A new amphiphilic zinc phthalocyanine (TAZnPc) containing long alkyl chains covalently linked to TAZnPc macroring was synthesized. Multilayers were deposited on hydrophobic ChF2 slide. IR spectrum of solid and LB film were studied. The orientation of long hydrocarbon ehain in the films was characterized by Fourier-transform IR (FT-IR) method. The result showed that the TAZnPc macroring was nearly parallel to the slide while the hydrocarbon chains inclined on the substrate at an angle of about 30°with respect to the substrate surfsee
