基于蒽基联脒（1）和二羧酸的结合实验，观察到即使在竞争性质子溶剂（MeOH）中也形成稳定的“脒-羧酸盐”盐桥。通过DOSY NMR、ESI-Mass、滴定实验和单晶X-射线分析证实了二脒1和二羧酸的1：1结合复合物的形成。类似地，在MeOH溶液中形成的“脒-膦酸盐”盐桥也被证明由二脒1和二膦酸的络合。
The formation of a stable ‘amidinium-carboxylate’ salt bridge, even in a competing protic solvent (MeOH), was observed based on the binding experiments of anthracene-based diamidine (1) and dicarboxylic acids. The formation of 1:1 binding complexes of the diamidine1and dicarboxylic acids was confirmed by DOSY NMR, ESI-Mass, titration experiments and a single crystal X-ray analysis. Similarly, the formation of the ‘amidinium-phosphonate’ salt bridge in the MeOH solution was also evidenced by the complexation of the diamidine1and diphosphonic acids.
