摘  要:研究了两亲性卟啉5,10,15,20-四-(4-N,N,N-二甲基十六烷基氨基苯基)卟啉(TDMC16PP)在气/液界面上的成膜性能,制备了其多层LB膜.用UV-Vis吸收光谱、荧光光谱、偏振UV-Vis吸收光谱和小角X射线衍射对LB膜进行了测试表征.结果表明:两亲性卟啉TDMC16PP具有良好的成膜性能,其LB膜性质稳定,有较好的结构均匀性和周期性.在LB膜内,脂肪链并不是直立的,卟啉大环平面与基片平面成42.5°排列.The film forming properties of 5,10,15,20 tetra (4 N,N,N dimethylhexadecyl aminophenyl) porphyrin (TDMC 16 PP) on the air/water interface was studied. Multilayers of amphiphilic porphyrin were built up on the glass and quartz substrate. The structure of LB films was characterized by UV Vis absorption spectra, polarized UV Vis absorption spectra, fluorescence spectra, and low angle X ray diffraction (LAXD). The experimental results indicated that TDMC 16 PP has good film forming performance, TDMC 16 PP LB films have good stability, homogeneity, and periodicity, the long alkyl chains are not straight and the porphyrin macroring in LB films lay on the substrate with a tilted angle 42.5°.
