Anderson 类型 polyoxometalate 被在双方上使用腺嘌 covalently 装饰。通过阳离子替换,我们为超分子的胶化与长烷基链获得了一块新混合积木。根据氢结合的合作效果内部方面烷基链的腺嘌单位和货车 der Waals 相互作用, DODA3 [A-MnMo6-A ] gelator 能稳定溶剂并且进含纤维的结构自我装配,形成超分子的胶化。另外,可逆大音阶的第五音胶化转变被控制环境温度完成。扫描电子显微镜学,传播电子显微镜学和 X 光检查衍射被用来描绘胶化形态学和结构。作为结果,我们建议了胶化形成和大音阶的第五音胶化转变的可能的机制。
An Anderson-type polyoxometalate was covalently decorated by using adenine on both sides. Through cation substitution, we obtained a new hybrid building block with long alkyl chains for supramolecular gels. According to the synergetic effect of hydrogen bonding of inter adenine units and van der Waals interaction of side alkyl chains, the DODA3[A-MnM%-A] gelator can stabilize solvent and self-assemble into fibrous structure, forming supramolecular gel. In addition, the reversible sol-gel transformation was achieved by controlling environmental temperature. Scanning electron microscopy, transmission electron microscopy and X-ray diffraction were used to characterize the gel morphology and structure. As a result, we proposed the possible mechanism of gel formation and sol-gel transformation.
