5,10,15,20-四(对-乙酯苯基)卟啉LB膜的结构

ON THE STRUCTURE OF LB FILM OF 5,10,15,20-TETRA(p-ETHOXYCARBONPHENYL)PORPHYRIN

对卟啉类化合物LB膜的结构、电性质和气敏性的研究已见报道。本文利用膜天平和UV-Vis分光光度计研究了标题化合物在气-液界面上的成膜特性、分子间相互作用和LB膜的结构。5,10,15,20-四（对-乙酯苯基）卟啉（TPEPP）由5,10,15,20-四（对-氰苯基）卟啉和乙醇酯化得到。元素分析测定值与计算值相符。λ（CHCl3,nm）:421,515,550,590,645;

The composition and structure of the title compound are verified by elemental analysis,UVVis and IR spectra. It forms a well-behaved monomolecular layer at the air-water interface. The surface pressure-molecular area isotherms depend on the pre-treatment. The UV-Vis spectra of the LB film indicate that molecular interaction come mainly from the same layer. Polarized UV-Vis spectra show that the porphyrin rings in the LB film are tilted to the film plane.
