Abstract
Abstract A flexible metal‐organic framework, {[Mn 2 (2,6‐ndc) 2 (bpda) 2 ]⋅5DMF} n ( 1 , 2,6‐ndc=2,6‐naphthalene dicarboxylate, bpda= N,N′ ‐bis(4‐pyridinyl)‐1,4‐benzene dicarboxamide) was successfully synthesized under solvothermal conditons. 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 framework was verified by in‐situ temperature‐dependent PXRD studies. The regular arrangement of the amide groups provided significant amide‐CO 2 and possible amide‐CO 2 ‐CO 2 cooperative effects that enhanced the adsorption of CO 2 molecules. Significantly, the findings show that the amide‐CO 2 interactions induced gate‐opening behavior. Introduction
