题 目：Heterogeneity within Order: Integration of Multi-functionalities in a MOF Platform
As a new emerging class of highly ordered porous materials, metal–organic frameworks (MOFs) have attracted broad research interests in the last two decades.
Their modular nature imparts designable topology, adjustable porosity, tunable functionality, and variable surface moieties within a single material, which have potential applications in many areas including gas storage, separation, and catalysis.
Constructing MOFs from multiple components is a pathway to achieve sophisticated applications which require different functionalities in highly ordered crystalline materials. It is still a challenge to synthesize multi-functional MOFs with desired placement or distribution of functionalities. Our research aims to develop kinetic and thermodynamic analysis for the design and synthesis of MOFs with multiple functionalities. In this presentation, three strategies will be introduced to realize “heterogeneity within order” in MOFs including 1) thermodynamically guided synthesis of mixed-linker MOFs, 2) kinetically controlled linker installation and cluster metalation towards mixed-linker and mixed-metal MOFs, and 3) linker labilization to create hierarchically porous MOFs by introducing crystal defects.
