Efficient conversion of carbon dioxide (CO2) into high-value chemicals is viewed as one the most promising approaches for solving problem an energy shortage and serious environment pollution. However, design synthesis confined multifunctional catalysts with in situ engineered task-specific sites nanoporous environments remain a complex challenging task due to lack in-depth understanding their structure reaction mechanism. Herein, we report highly robust 2D framework {[Tm(HFPDC)(DMF)2]·DMF·H2O}n (NUC-120) (H4FPDC = 4,4′-(4-(4-fluorophenyl)pyridine-2,6-diyl)diisophthalic acid). The thermally activated host [Tm(HFPDC)]n (NUC-120a) has following two merits: (i) structure, (ii) massive quantity functional sites. Moreover, NUC-120 NUC-120a display high thermal chemical stability, which have been proved by TGA soaking experiments acid–base water organic solvents. Catalytic that NUC-120a, presence n-Bu4NBr cocatalyst could efficiently catalyze coupling CO2 epoxides under comparatively mild conditions. Furthermore, also displays catalytic performance Knoevenagel condensation reactions aldehydes malononitrile, should be because coexisting Lewis acidic basic can separately activate aldehyde malononitrile molecules. Thereby, this work further provides insight desired materials generated using existing suitable secondary building units (SBUs) meticulously regulating growth environments.
