摘要 

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。

Abstract

Pyridine dicarboxamide derivatives with different side chains, including 4a/4b/4c, 5 and 9, were synthesized and their gelation properties were tested. The results showed that these compounds can form stable gels in some organic solvents and the structure of side chain affects gelling property greatly. Ultra-violet-visible spectroscopy and Fourier transform infrared spectroscopy were used to investigate the driving force of gelation. Gels from these compounds are responsive to fluorine anion, indicating the existence of hydrogen bond. The morphologies of xerogels were observed with scanning electron microscopy. Teas parameters of 9 and eight organic solvents were calculated and a Teas plot was constructed. The validity of expected gelation domain in the Teas plot was verified.
