Solvent-mediated subcomponent self-assembly of covalent metallacycles for hierarchical porous materials synthesis

Abstract

We report a solvent-mediated subcomponent self-assembly strategy for synthesizing tetranuclear and triangular covalent metallacycles. The results demonstrate that the polarity of solvent significantly influences the structural outcome of metallacycles, and the square-shaped metallacycles can serve as building blocks for the construction of hierarchical porous materials such as metallacycle-based hydrogen-bonded organic frameworks (mHOFs) and metal-organic frameworks (mMOFs).
