环糊精衍生物与偶氮苯Langmuir复合膜的界面自组装与主客体识别研究
Interfacial self-assembly and host-guest recognition of Langmuir composite films via cyclodextrin derivative and azobenzene compound
摘要
Abstract
Cholesterol-modified beta-cyclodextrin derivative (abbreviated as CD-CHOL) and the azobenzene-modified poly(acrylic acid) compound (abbreviated as PAA-Azo) have been designed and synthesized.And the Langmuir films have been successfully prepared by the interfacial self-assembly, which could be verified by the surface pressure-area isotherms.Atomic force microscopy was utilized to characterize the morphologies of Langmuir films.In addition,the process of self-assembly and host-guest recognition between cyclodextrin and azobenzene segments have been investigated by various methods, including UV-Vis,CD,FT-IR,and XPS spectra.The experimental data indicated that the CD-CHOL Langmuir films could be prepared stably both on pure water subphase and PAA-Azo subphase.At the same time, the molecules recognition occurred between cyclodextrin and azobenzene groups.The present research work would provide beneficial exploration for the research of interfacial self-assembly and host-guest recognition of cyclodextrin derivatives.关键词
