摘要：
A flexible metal-organic framework, {[ Mn-2(2,6-ndc)(2) (bpda)(2)] . 5DMF}(12) ( 1, 2,6-ndc=2,6-naphthalene dicarboxylate, bpda= N, N'-bis(4- pyridinyl)-1,4-benzene dicarboxamide) was successfully synthesized under solvothermalconditons. A structural analysis showed that compound 1 is comprised of a 2-fold interpenetrating network with amide groups exposed in the channels. The flexibility of the 2-fold interpenetrating frame-work was verified by in-situ temperature-dependent PXRD studies. The regular arrangement of the amide groups provided significant amide-CO2 and possible amide-CO2-CO2 cooperative effects that enhanced the adsorption of CO2 molecules. Significantly, the findings show that the amide-CO2 interactions induced gate-opening behavior.
