通过点击化学合成了新型的多链分子,该多链分子带有一个中心的双苯磺酰基部分,该部分在两端通过酰胺或酯键连接到三唑树枝状分子上。在体相状态下,只有一种烷基链最长的酯类化合物能自组装成p6mm柱状相,其它化合物均为非介晶。这些多链体在极性溶剂中比在非极性或极性较低的溶剂中可以形成具有更有序形态的有机凝胶。在DMF溶剂中,酯类化合物形成的凝胶具有球形花状形貌,而酰胺类化合物形成的凝胶具有纳米片形貌。酰胺聚链也可以作为化学传感器,用于高选择性地检测金属离子。结果表明,键的极性和溶剂的极性对超分子纳米结构的形成有显著影响。
Novel polycatenars bearing a central bisphenyl sulfonyl moiety connected to the triazole dendrons at both ends through amide or ester linkages were synthesized via click chemistry. In their bulk states, only one ester compound with the longest alkyl chains can self-assemble into p6mm columnar phase, all the other compounds are nonmesogens. These polycatenars can form organogels with much more ordered morphologies in polar solvents than in apolar or less polar solvents. In DMF solvent, gels with spherical flower-like morphologies are formed by ester compounds, while gels with nanosheet morphologies are formed by amide compounds. The amide polycatenars can also act as chemosensors for detecting metal ions with high selectivity. The results showed that both the polarities of the linkages and the polarities of the solvents dramatically influenced the creation of supramolecular nanostructures.
