合成了系列不同侧链的吡啶二酰胺类衍生物4a、4b、4c、5、9。测试并对比了其凝胶性能,结果表明该类化合物在有机溶剂中具有较好的凝胶性能且侧链对其性能具有很大影响。通过紫外光谱及红外光谱测试研究了系列化合物的成胶驱动力;阴离子测试结果表明该系列凝胶具有阴离子响应特性,同时验证了氢键作用的存在。运用扫描电子显微镜观察并分析了凝胶的微观形貌。计算了凝胶因子9和8种溶剂的梯氏参数,绘制了相应的梯氏参数图,并对预测成胶区域的有效性进行了验证。
A series of pyridine diamide derivatives 4a, 4b, 4c, 5 and 9 with different side chains were synthesized. The gel properties of the compounds were tested and compared. The results show that the compounds have good gel properties in organic solvents and the side chains have great influence on their properties. The driving forces for gelation of the compounds were investigated by UV-vis and infrared spectroscopy. The anionic test results showed that the gels had anion-responsive properties and the existence of hydrogen bonding was verified. The morphology of the gel was observed and analyzed by scanning electron microscopy. The parameters of the ladder of 9 and 8 solvents were calculated and the corresponding parameters of the ladder were plotted. The validity of the predicted gelling area was also verified.
