(C14IP)6 and (C18IP)6 hexamers assembled to form the tubular molecular assembly stabilized by intermolecular–N–H⋯O = hydrogen-bondinginteractions along the tube growth direction, where H2O molecules were contained within the hydrophilic space. On the other hand, the N–H⋯O = hydrogen-bondinginteractions between the 1D zig-zag (CnIP)∞ chains formed a layer-type molecular assembly of the La-phase in the
制备了间苯二甲酸衍生物 ( CnIP ),其在 5 位具有可参与氢键合的烷基酰胺链 (-CONHC n H 2 n +1 : n = 6、10、14 和 18),并对其氢键进行了评估-用于有机凝胶化和液晶形成的键合分子组装结构。氢键羧酸 (-COOH) 基团形成环状 ( CnIP ) 6六聚体或一维 (1D) 之字形 ( CnIP ) ∞链。尽管在带有烷氧基的间苯二甲酸衍生物中既没有观察到有机凝胶化也没有观察到液晶形成(-OC 14 H 29) 链,C14IP和C18IP衍生物可以通过分子间 N-H⋯O = 酰胺型氢键相互作用形成有机凝胶和液晶态。在水合的(C14IP) 6 ·(H 2 O) n和( C18IP ) 6 ·(H 2 O) n中观察到盘状六方柱状液晶(Col h )相,而在水合( C14IP ) 6 ·(H 2 O) n中观察到盘状六方柱状液晶(Col h )相,而薄片型液晶(La
