| 摘 要： | 以甘氨酸为连接臂、顺反丁烯二酸为功能基团设计合成了2种具有不同立体异构连接臂的A(LS)2 型双胆固醇类小分子胶凝剂MA-C和FA-C.考察了MA-C和FA-C对30种常见有机溶剂的胶凝能力.结果表明,MA-C和FA-C的胶凝能力及其所形成凝胶的性质依赖于胶凝剂分子的立体异构.特别是MA-C能使CCl4室温胶凝,而且所...

| Abstract: | Two cholesterol-containing low molecular mass gelators(LMMGs) of A(LS)2 type with glycin in the linkers and butene diacid in the A part were prepared.Their gelation abilities were evaluated in 30 commonly used organic solvents.It was found that the change in the stereo-structure of the linker had a dramatic effect upon the gelation behaviors of the gelators.Interestingly,MA-C gelated CCl4 spontaneously at room temperature,and the gel as-formed exhibited good thermal stability and thixotropic property as rev... |
