Dicopper(ii) paddle-wheel metal–organic frameworks for high propyne storage under ambient conditions†
Abstract
Fluorinated dicopper(II) metal–organic framework JXNU-16F with 1,3,5-tri(3,5-bifluoro-4-carboxyphenyl)benzene ligands and nonfluorinated JXNU-16 exhibit high propyne uptakes of 443 and 496 cm3 g−1 under ambient conditions, respectively. Their remarkable propyne uptakes result from suitable pore spaces and strong propyne⋯propyne interactions amongst the adsorbed propyne molecules, as revealed by computational simulations.
