π-共轭三苯基苯衍生物的合成及其胶凝性能
Synthesis of π-Conjugated Triphenylbenzene Derivatives and Their Gelling Property
摘要
Abstract
A series of discotic molecules containing triphenylbenzene group and three monochains were synthesized and their self-assembly properties were studied. These derivatives formed stable gels in many low polarity organic solvents. The lamellar and fibrous aggregate morphologies of the xerogels and the layered structure of the gel aggregates were studied by scanning electron microscopy (SEM) and small angle X-ray diffraction (SA-XRD), respectively. Fourier transform infrared (FT-IR) spectroscopy and UV-Vis absorption spectroscopy revealed that the hydrogen bonding and π-π interactions were the main driving force for the formation of a self-assembled gel. During gel formation, the gelator molecules self-assemble into ordered lamellar aggregates in organic solvents through a π-π conjugation stacking effect and hydrogen bonding. The ordered lamellar aggregates are juxtaposed and interlocked by van der Waals interactions to form sheet-like structure or fiber superstructure and finally immobilize into the organic liquids.关键词
