卟啉、酞菁L-B膜中取代基的定向作用研究
摘要:
由Π-A 曲线研究了五种具有不同取代基的卟啉、酞菁金属配合物不溶物膜的水/空气界面性质, 根据分子截面积和分子模型推断了单层膜中卟啉、酞菁环的可能取向及取代基的定向作用. 以偏振紫外测定了L-B 多层膜中大环的取向, 结果表明卟啉, 酞菁环以与它们在亚相表面相同的取向转移到固体基片上, 证明了取代基的性质和致目不同对分子大环的定向作用不同.

Studies on the Oriented Effect of Substituents in the L-B Films Built up of Metalloporphyrins or Metallophthalocyanines
Abstract:
The monolayers on the water surface were studied by pressure-area isotherms, with five metalloporphyrins and metallophthalocyanines bearing differential substi-tuents. From the limiting areas together with the molecular model, probable orientation of maerocycle in the monolayer and the oriented effect of substituents upon the mac-rocycles were considered. These monolayer were transferred to the substrates by L-B method. The UV-vis spectra of the L-B films and in solution were measured. The results showed that there were aggregates in the L-B films of metallophthalocyanines while not in the L-B films were examined by polarized UV-vis absorbance. It was confirmed that orientation in L-B films inherently depends upon those molecular states spreading monolayers on the water surface. According to this result, by introducing appropriate substitutents into porphyrin or phthalocyanine ring the molecular orientation and stracking in the L-B films could be controlled.
