这一观点提出了金属有机骨架化合物（MOF）形成的合理且直观的机制。一旦金属盐溶解在水或非水溶剂中，就形成可溶性金属络合物。了解这种复合物如何与溶剂介质中的有机基团结合对于理解这些分子通过水解和缩合转化为最终固体至关重要。人们强烈认为，当零点电荷分子 (pzc) 在等电点形成时会发生缩合。使用这种机制可以很容易地解释文献中的几个例子。
This perspective proposes a rational and intuitive mechanism for the formation of metal-organic framework compounds (MOF). As soon as a metal salt is dissolved in water or a nonaqueous solvent, a soluble metal complex is formed. Knowing how this complex organizes with the organic groups in the medium of the solvent is crucial to understanding the transformation of these molecules into the final solid through hydrolysis and condensation. Condensation is strongly believed to occur when point zero charge molecules (pzc) are formed at the isoelectric point. Several examples from the literature are readily explained using this mechanism.
