Precise engineering of building unit apportionment in proteins and nucleic acids is essential for chemical processes in cells such as recognition, bio-catalysis and information storage. The well-defined sequences and distributions have inspired researchers to develop tailored architectures with controllable heterogeneity in polymers, nanomaterials and porous materials. For example, the construction of multi-component hybrid metal-organic frameworks (MOFs) has led to fascinating advances in fields such as gas separation, size-selective catalysis, and controlled drug delivery. Introduction of sophisticated functionalities in MOFs or MOF composites typically requires hierarchical or other complicated structures and specific sequences of multiple building units within the crystals. Herein, we exhibit the design and construction of multivariate hierarchical metal-organic frameworks through the subsequent incorporation of organic linkers and inorganic clusters into MOF mesopores. This kinetic synthetic tool was utilized for the successful retrosynthesis of multi-component MOFs, and can achieve enhanced performance over heterogeneous catalysis.
