Abstract

While significant progress in covalent organic frameworks (COFs) has been made in recent years, the construction of COFs with heterogeneous porosity remains a great challenge. In this communication, we report two novel 2D heteropore COFs which bear two kinds of hexagonal micropores with different shapes and sizes. They have been constructed by the condensation of monomers with C2v- and D3h-symmetry, and their structures have been confirmed by PXRD studies, synchrotron SAXS experiments, theoretical simulations and pore size distribution analyses.
