【摘要】 合成了2个系列的芳香双硫脲类化合物6a～6d和7a～7d,对它们的凝胶性能和凝胶结构进行了测试。凝胶测试表明,化合物6a～6d相比于7a～7d具有较好的凝胶性能。运用SEM、1HNMR、FT-IR、XRD对凝胶的基本结构进行了分析,结果表明分子间氢键是此类化合物形成凝胶的重要驱动力,化合物6c的干凝胶具有六方柱状结构而7c的是层状结构。更多还原

【Abstract】 Two series of bis-thiourea derivatives 6a—d and 7a—d were synthesized and their gelling properties were checked.The results showed that 6a—d had stronger gelation ability than 7a—d.The structures of gels were investigated using concentration-dependent SEM,1H NMR,FT-IR and XRD.It was found that intermolecular hydrogen bonds were the main driving force for the gelation.The results of XRD suggested that the dry gels of 6c had columnar hexagonal structure while 7c was layered.更多还原
