摘　　要：研究了两亲性卟啉５，１０，１５，２０－四－（４－十六烷基吡啶基）卟啉溴化物在气－液界面上的成膜性能，制备了其ＬＢ膜。用扫描隧道显微镜和ＵＶ－Ｖｉｓ光谱，荧光光谱，小角Ｘ射线衍射等实验方法研究了ＬＢ膜的形貌和卟啉大环分子在ＬＢ膜中的排列、取向和分子间的相互作用。结果表明，制备的ＬＢ膜结构均匀，性能稳定。在ＬＢ膜内，脂肪链并不是直立的，卟啉分子大环几乎平躺在基片上。The film forming properties of 5,10,15,20 tetra (4 hexadecylpyridiniumyl)porphyrin bromide(TC 16 PyP)on the air/water interface were studied.LB films of the amphiphilic porphyrin were prepared on the glass,quartz and SnO 2 OTE substrates.The morphology and structure of TC 16 PyP LB films were characterized by scanning tunnelling microscope,UV Vis absorption spectra,fluorescence spectra and low angle X ray diffraction.The experimental results indicated that the amphiphilic porphyrin TC 16 PyP has good film forming properties on the air/water interface,its LB films are stable,in TC 16 PyP monolayer or LB films the long alkyl chains are not straight and the porphyrin macroring is lying nearly parallel to the substrate surface.
