摘　　要：设计合成了一种含有蒽醌酰亚胺电致变色基团的含糖小分子有机凝胶因子，N-（4-苯基-2，3，4，6-四乙酰基-β-D-葡萄糖苷）-蒽醌-2，3-二羧基酰亚胺（AGC）。光谱电化学表征发现当还原到一价自由基阴离子的时候，AGC在600-1200nm的近红外区出现了明显的吸收，说明蒽醌酰亚胺基团保持了其特有的电致变色性质。12种极性不同的溶剂被用于测试AGC的凝胶性能，发现其在乙二醇、正丁醇、正庚醇和对二甲苯中能够形成稳定的凝胶，说明得到一种新颖的功能化小分子有机凝胶因子。A sugar-based organogelator containing electrochromic anthraquinone imide, N-（4-phenyl-2,3,4,6- tetraacetyl-β-D-glucosyl）- anthraquinone 2, 3-dicarboxylic imide （AGC）, has been designed and synthesized. With spectroelectrochemistry measurement, it was found that the radical anion state of AGC displays intensive absorption signal in the near-infrared region of 600-1200 nm, indicating that AGC maintains the electrochromic property of anthraquinone imide. Twelve solvents with different polarity were used to evaluate the gelation ability of AGC. Four of them were found to be gelled by AGC, which were glycol, n-butanol, n-heptanol, and p-xylene, implying a novel functional organogelator was obtained.
