Abstract

Chemical environment of pores is important for various applications of porous solids. Thanks to reticular chemistry, metal-organic frameworks (MOFs) became a versatile platform targeting numerous applications through multiple functionalization. Although multivariate MOFs often display novel properties, identifying and manipulating pore types remain a daunting challenge. Here, we present an isoreticular series of Zr-based metal-organic polyhedra (MOPs) as a porous platform to achieve controllable intrinsic pores. Two multivariate synthetic approaches were demonstrated: a mixed-cage strategy where functionalized cages are mixed, compared to the conventional mixed-linker strategy, which yields a random distribution of functionalities. A remarkable difference in functionality assembly was achieved between the strategies with complexity increasing from binary to senary systems. More interestingly, distinct photophysical properties were observed between mixed-linker and mixed-cage samples attributed to radiative decay kinetics. This study highlights the potential of MOPs as a unique multivariate porous platform with tunable component assembly to study the emerging properties of multivariate porous solids.
