以凝胶因子N-己基-2,4-(3,4-二氯苯亚甲基)-D-葡萄糖酸酰胺为基础,合成出了3种新的凝胶因子,并对4种凝胶因子的乙酸丁酯凝胶的流变学性能进行了测试,发现它们均具有触变性,而N-(3-丙氧基)丙基-2,4-(3,4-二氯苯亚甲基)-D-葡萄糖酸酰胺凝胶因子的乙酸丁酯凝胶可过度恢复,而其它3种凝胶仅能部分恢复。为了探讨其中原因,分别对4种凝胶进行了红外光谱测试和荧光光谱测试,发现侧链中的氧原子在凝胶恢复过程中参与到了氢键形成从而加强了分子间的氢键作用,从而使其凝胶的机械性能在恢复后有所增强。而π-π堆积恢复后的减少,导致了其他3种凝胶因子的乙酸丁酯凝胶不能完全恢复。
Based on the gel factor N-hexyl-2,4- (3,4-dichlorobenzylidene) -D-gluconic acid amide, three new gel factors were synthesized, and four kinds of gels The rheological properties of the butyl acetate gel were tested and found to be thixotropic, whereas N- (3-propoxy) propyl-2,4- (3,4-dichlorobenzylidene) ) -D-gluconamide gel factor butyl acetate gel can be over-restored, while the other three gel only partially recovered. In order to explore the reasons, the four kinds of gels were tested by FTIR and fluorescence spectra respectively. It was found that the oxygen atoms in the side chains were involved in the formation of hydrogen bonds in the process of gel recovery, which enhanced the intermolecular hydrogen bonding. The mechanical properties of the gel have been enhanced after recovery. However, the decrease of π-π accumulation after recovery led to the incomplete recovery of butyl acetate gel of the other three gel factors.
