- Abstract
A dual-channel material of {[(CH3)2NH2][Yb3(BDCP)2(H2O)3]·2DMF·3H2O}n (NUC-58) has been generated from the combination of wave-like [Yb2(CO2)6(H2O)2]n chains and [Yb(CO2)4(H2O)] units with the aid of 2,6-bis(2,4-dicarboxylphenyl)-4-(4- carboxylphenyl)pyridine, which has excellent physical and chemical properties including a larger specific surface area, high porosity, water resistance and thermal stability. NUC-58 is a rarely reported microporous MOFs with solvent-free dual channels. Thanks to its coexistence of Lewis acid–base sites including rich hexa/hepta-coordinated Yb3+ ions, C = O groups from μ1−η1:η1 CO2−, and Npyridine atoms, NUC-58 displays highly catalytic activity on the cycloaddition reaction of epoxides and CO2 into related cyclic carbonates under mild solvent-free reaction conditions. In addition, NUC-58 could be used as a fast, sensitive and highly efficiency sensor for Cu2+ detection in aqueous solution. Therefore, the work shows that microporous MOFs assembled from pyridine-containing polycarboxylic acid ligands and rare earth ions can serve as excellent catalytic and luminescent materials. A highly robust ytterbium (III)-organic framework of {[(CH3)2NH2]2[Yb3 (BDCP)2(NO3)(OH2)3]·2DMF·3H2O}n (NUC-58) for efficiently catalyzing the chemical fixation of CO2.
