基于萘酰亚胺的功能凝胶因子的合成及其凝胶性能
Synthesis and gel properties of functional gelators based on naphthalene-diimide
摘要
Abstract
A new triazine intermediates with amide group was synthesized from cyanuric chloride, and NDI-M was obtained by condensation of the intermediates and 1,4,5,8-naphthalenetetracarboxylic dianhydride. The molecular structure of NDI-M was confirmed by 1HNMR, 13CNMR and FTIR. Gel properties were tested by the stable-to-inversion of vial method, and micromorphology of gels was observed by SEM. Photophysical properties were investigated by UV-Vis absorption spectrum and fluorescence spectrum. The results show that NDI-M can form thermal reversible gels in solvents, such as toluene, xylene, butyl methacrylate and butyl acetate. All critical gelation concentrations(CGC) reach 20 mmol/L but butyl acetate is 30 mmol/L. Gels present different microstructures in various solvents. Compared with the spectral properties of the solution,the stokes shift of gels significantly increases and the spectral properties of gels formed in various solvents show obvious differences.关键词
