合成了一个苯并21-冠-7-柱[5]芳烃杂二主题主体分子(1),二级铵盐是21-冠-7大环的合适客体,而柱[5]芳烃空腔可以强络合中性客体基元5-(1H-1,2,3-triazol-1-yl)pentanenitrile(TAPN),因此选择含有2个TAPN的客体2和含有2个二级铵盐的客体3作为连接体,依靠二级铵盐?21-冠-7和中性客体?柱[5]芳烃正交主客体作用,构筑了一个三组分超分子聚合物(1,2和3的摩尔比为1∶0.5∶0.5),该组装体的形成得到了1H-NMR、DOSY、黏度和SEM等手段的表征?所构筑的超分子聚集体是浓度依赖的,其形成超分子聚合物的临界浓度为49 mmol/L.
A benzylated 21-crown-7-column [5] arene complex is proposed as the target host molecule (1), and the secondary ammonium salt is a suitable guest for the 21-crown-7 macrocycle. Strongly complex neutral guest motif 5- (1H-1,2,3-triazol-1-yl) pentanenitrile (TAPN), so choose 2 containing two TAPN guest 2 and 2 containing two guest 3 As a linker, a three-component supramolecular polymer (molar ratio of 1, 2 and 3) was constructed by orthogonal host-guest interaction between the secondary ammonium salt 21-crown-7 and the neutral [5] 1: 0.5: 0.5). The formation of this assembly was characterized by 1H-NMR, DOSY, viscosity and SEM. The supramolecular aggregates formed were concentration-dependent and formed a critical concentration of supramolecular polymer 49 mmol / L.
