Reactive alcohol functionality has been incorporated into a self-assembled M2L3 mesocate. Post-synthetic modification of this complex with suitable isocyanates is not only possible, but is self-catalyzed by multiple internal hydrogen bonds from the self-assembly. As the metal-ligand coordination is reversible at elevated temperature, the isomeric distribution of product changes upon reaction, due to the different steric bulk conferred on the assembly after the modification.
反应性醇官能团已被引入到一种自组装的M2L3介孔配合物中。用合适的异氰酸酯对该配合物进行后合成修饰不仅是可行的，而且会被自组装过程中多个内部氢键自催化。由于金属-配体配位在高温下是可逆的，反应后产物的异构体分布会发生变化，这是因为修饰后组装体具有不同的空间位阻。
