摘要/Abstract

摘要： 利用混合LB技术,在脂肪酸与5,10,15-三苯基-20-(4-dl-α-苯丙氨酰氨基)苯基卟啉(简称TPPP)混合单分子膜内制备了二维微晶畴结构.原子力显微术观测表明;对于长链脂肪酸的情况;膜中形成了处于液态凝聚相的脂肪酸的微晶畴结构;而在短链脂肪酸的情况下,膜中出现的则是处于液态扩张相的TPPP的微晶畴结构.简要讨论了这一结构的实际应用.

Abstract: Two-dimensional domain structures were prepared in the mixed monolayer films composed of fatty acid and 5, 10, 15-triphenyl -20-(4-dl-α-phenylalanylamindo) phenyl porphyrin(TPPP) by the mixed Langmuir-Blodgett technique. Through atomic force microscopy studies, we observed the fatty acid domains in the liquid-condensed phase for the conditions of long alkyl chain. By shortening the length of the hydrocarbon chain, TPPP domains in the liquid-expanded phase were observed. A brief discussion about the practical usage of this kind of structures was presented in this paper.

Key words: atomic force microscopy, mixed monolayer film, domain, liquid condensed phase, liquid-expanded phase
