摘要
The transformation of a Palladium-based metal-organic cage to a structurally similar one by direct ligand replacement usually leads to unwanted ligand scrambling. In this work, an intermediate ligand with different shape and basicity from the initial/final ones was introduced to avoid ligand scrambling to achieve the efficient indirect cage-to-similar-cage transformation. Compared with the direct transformation, the stepwise conversion has the advantages of high efficiency(93%) and simple workup.
