The stability of five different [Pd (N-donor) ] assemblies was examined by performing disassembly experiments with pyridine and with trifluoroacetic acid. Pyridine-induced disassembly was found to be most pronounced for Pd complexes containing N-donor ligands of low basicity. At the same time, these assemblies displayed high acid resistance. The contrasting stability in the presence of acid or pyridine can be used for the pH-controlled switching between different metallosupramolecular structures.
通过用吡啶和三氟乙酸进行拆卸实验，研究了五种不同的[Pd（N-供体）]组装体的稳定性。发现对于含有低碱性 N-供体配体的 Pd 配合物，吡啶诱导的拆卸最为明显。同时，这些组装体显示出高耐酸性。在酸或吡啶存在下的稳定性差异可用于不同金属超分子结构之间的 pH 控制切换。
