A series of new viologen analogues bearing two ammonioalkyl groups (2–4) were synthesized in order to study their complexation with bis(18-crown-6)stilbene (1b). Electronic spectroscopy and 1H NMR measurements show that in acetonitrile, bis(crown) stilbene 1b forms highly stable 1 : 1 and 2 : 1 charge-transfer (CT) complexes with π-acceptors 2–4 owing to host–guest bonding. The influence of geometric
一系列新的紫精类似物带有两个氨溶基团(2 - 4),以研究它们的络合与双合成(18-冠-6)芪(1B)。电子光谱学 和 1 H NMR 测量表明 乙腈,双(冠)芪1B形式高度稳定的1:1和2:1的电荷转移(CT)配合物的π受体2 - 4由于主-客体结合。讨论了几何和电子因素对复合物形成常数的影响。超分子CT络合物的结构在1 H和13 C NMR 在溶液和固态下获得的数据。 X射线衍射数据适用于1b和型号四甲氧基sti 也有报道。
