Abstract

A water stable porous 3D metal-organic framework, [Cu₃L₂(μ ₃-OH)₂(μ ₂-H₂O)]·2DMA (1, mother crystal, H₂L = 2,2’-dinitrobiphenyl-4,4’-dicarboxylic acid, DMA = N, N-dimethylacetamide), shows unprecedented irreversible solvent-induced substitutions of bridging aqua ligands and guest-exchanges in single-crystal-to-single-crystal (SCSC) transformations at room temperature (RT), producing quantitatively three daughter crystals, [Cu₃L₂(μ ₃-OH)₂]·2S (2: 2A, S = acetone; 2B, S = 2-propanol; 2C, S = 2-butanol), which exhibit reversible interconversion by guest-exchanges at RT in SCSC transformations. MOF 1 shows excellent separation selectivity (128) of CO₂/N₂at RT and is a better sorbent of micro-solid-phase extraction (μ-SPE) than currently known benchmark ZIF-8.
