A new class of efficient low-molecular-weight gelators composed of a 2-substituted anthraquinone and a hydrazide subunit were synthesized, and the structure–property relationships with respect to their gelation abilities in organic solvents were investigated. The toluene gels showed exceptional thermal stability. Interestingly, it was also found that the ultrasound radiation could promote 1b–e to form
合成了一类新型的由2-取代的
蒽醌和酰
肼亚基组成的高效低分子量胶凝剂,研究了它们在有机溶剂中的胶凝能力与其结构-性质的关系。
甲苯凝胶显示出优异的热稳定性。有趣的是,还发现超声辐射可以促进1b - e形成稳定的有机凝胶,而不是在极性溶剂中形成沉淀,并且超声可以显着诱导
吡啶中组件的形态变化。此外,可通过添加TFA和
TEA来实现可逆的凝胶至溶胶相变。胶凝剂1b – e 进一步显示了芳香族溶剂或
氯代
烷烃与
水的混合物的选择性凝胶化。
