Two-dimensional dual-pore covalent organic frameworks obtained from the combination of two D_2h symmetrical building blocks

Abstract

A strategy to construct covalent organic frameworks (COFs) bearing two different kinds of pores has been developed, by which two dual-pore COFs were fabricated through the condensation reactions of two D_2h symmetrical building blocks. The COFs exhibit good adsorption capacities for CO₂ and H₂.
