卟啉与花生酸混合LB膜研究

研究了具有四条长脂链的卟啉与花生酸混合物在气液界面的成膜性及ＬＢ膜．结果表明，卟啉与花生酸混合可形成稳定的单层膜，在混合ＬＢ膜中卟啉形成Ｂ带劈裂聚集体，花生酸的掺入对卟啉分子的有序排列和聚集作用没有影响．利用偏振紫外可见吸收光谱测量了膜中卟啉环的取向．

Studies on the Mixed LB Films of the Porphyrin and Arachic Acid

The LB films forming properties of the mixture of the porphyrin containing four long aliphatic chains and arachic acid have been studied. The results indicate that better mixed monolayer of the porphyrin and arachic acid can be prepared. The Bstate splitting aggregates of the porphyrin in the mixed LB films have been characterized, and the incorporated arachic acid has no influence on the arrangement and aggregation of the prophyrin molecules. The orientation of the prophyrin rings in the mixed LB films were examined by polarized UVvis spectra.
