溶剂调控谷氨酸衍生物自组装纳米结构的研究

摘要

The self▬assembly behavior of N,Nˊ▬diglutamate▬3,4,9,10▬peryleneimide(GP)were tuned by controlled ratio of wa▬ter in solvent• The self▬assembly structures were investigated by means of Scanning Electron Microscopy( SEM),Fourier Transform In▬frared Spectroscopy( FTIR)and Ultraviolet Spectra( UV)•The results demonstrate that solvent deeply affects the self▬assembly of GP molecules,which lead to different nanostructures• This phenomenon was due to the participation of water in self▬assembly of GP mole▬cules,thus tuned the interactions between molecules.%通过调节溶剂中水的比例来调控N，N＇-二谷氨酸-3，4，9，10-苝四甲酸二酰亚胺（ GP）的自组装行为•通过扫描电子显微镜（ SEM）、红外和紫外等手段对组装结构进行了表征•结果表明溶剂对N，N＇-二谷氨酸-3，4，9，10-苝四甲酸二酰亚胺（ GP）自组装过程影响较为显著，导致形成不同组装纳米结构•这归因于水溶剂参与了分子间的组装过程，从而调节了分子间的相互作用力•
