The association constants of the complexes formed by two hosts containing pyrrole, amide and azine (pyridine and 1,8-naphthyridine) groups and six guests, all monoanions (Cl−, CH3CO2−, NO3−, H2PO4−, BF4−, PF6−), have been determined using NMR titrations. The X-ray crystal structure of the host N2,N5-bis(6-methylpyridin-2-yl)-3,4-diphenyl-1H-pyrrole-2,5-dicarboxamide (1) has been solved (P21/c monoclinic
由包含吡咯、酰胺和吖嗪(吡啶和 1,8-萘啶)基团和六个客体的两个主体形成的复合物的结合常数,所有单阴离子(Cl-、CH3CO2-、NO3-、H2PO4-、BF4-、PF6- ),已使用 NMR 滴定法测定。主体 N2,N5-bis(6-methylpyridin-2-yl)-3,4-diphenyl-1H-pyrrole-2,5-dicarboxamide (1) 的 X 射线晶体结构已解析(P21/c 单斜晶系)空间群)。B3LYP/6-31G(d,p) 和计算是为了使实验关联常数中观察到的趋势合理化。
