A Diazo Linker Ligand Promotes Flexibility and Induced Fit Binding in a Microporous Copper Coordination Network.

ABSTRACT: Flexible organic linkers represent an intuitive and effective strategy to design flexible metal-organic materials. We report herein a systematic study concerning the effect of varying the central bond of mixed pyridyl-benzoate linkers, L, upon the flexibility of three isostructural kdd topology microporous coordination networks (CNs) of formula ML₂: X-kdd-1-Cu, 1 = L = (E)-4-(pyridin-4-yldiazenyl)benzoate; X-kdd-2-Cu, 2 = L = (E)-4-(2-(pyridin-4-yl)vinyl)benzoate; the previously reported X-kdd-3-Cu, 3 = L = 4-(pyridin-4-ylethynyl)benzoate. As revealed by single crystal x-ray diffraction (SCXRD) and gas sorption studies, X-kdd-1-Cu, exhibited gate-opening during CO₂ and hydrocarbon (C2 and C8) sorption experiments whereas the other two CNs did not. Insight into these p
