A new series of N-(thiazol-2-yl) benzamide derivatives were synthesized, characterized and investigated for their gelation behavior with the aim to elucidate the role of methyl functionality and multiple non-covalent interactions on gelation/non-gelation behavior using Crystal engineering approach. Interestingly, two amides, namely, 3-methyl-N-(thiazol-2-yl) benzamide (1c) and 3-methyl-N-(5-methylthiazol-2-yl)
合成,表征和研究了一系列新的N-(噻唑-2-基)苯甲酰胺衍生物的胶凝行为,目的是阐明使用晶体的甲基官能团和多种非共价相互作用对胶凝/非胶凝行为的作用。工程方法。有趣的是,两种酰胺,即3-甲基-N-(噻唑-2-基)苯甲酰胺(1c)和3-甲基-N-(5-甲基噻唑-2-基)苯甲酰胺(3c)对乙醇/水和甲醇/水混合物,稳定性好,最低胶凝剂浓度(MGC)低。胶凝剂(1c)的单晶结构显示出由π-π相互作用以及循环的N–H⋯N和S⋯O相互作用驱动的螺旋组装,而胶凝剂(1c)(3c)显示了没有任何π-π相互作用的2D氢键网络。
