Abstract

Zeolitic imidazolate frameworks (ZIFs) are a sub-class of metal-organic frameworks (MOFs). Although generally stable, ZIFs can undergo post-synthetic linker exchange (PSLE) in solution under mild conditions. Herein, we present a novel, solvent-free approach to post-synthetic linker exchange through exposure to linker vapor.

Keywords: ZIF-8; metal-organic frameworks; mixed-linker ZIFs; solvent-free modification; vapor-phase linker exchange.
