摘　　要：Rare earth metal-organic frameworks(RE-MOFs)have drawn wide attention owing to diverse network structures and various application prospects.However;due to the unpredictable formation of the nodes;it is still challenging to design novel RE-MOFs.A novel versatile strategy was developed employing a RE-acetate complex(RE2(CH_(3)COO)6·4H_(2)O)as a precursor to construct RE-MOFs.2D RE-MOFs(RE-DBP)and 3D RE-MOFs(RE-TCPP)could be obtained by using dicarboxylic porphyrin ligands H_(2)DBP and tetracarboxylic porphyrin ligands H_(2)TCPP;respectively.Ten RE-MOFs were further synthesized to verify the universality of the methodology.Highly crystalline RE-MOFs could also be prepared at room temperature via the developed strategy;which could significantly promote large-scale preparation and practical application of RE-MOFs.As proof of the concept;the performance of porphyrin-based RE-MOFs was investigated in the photocatalytic cycloaddition of CO_(2) with epoxides.Among the RE-DBP(Co)MOFs;Tb-DBP(Co)exhibited the best photocatalytic performance;which was also greater than that of the corresponding 3D MOF Tb-TCPP(Co)due to the optimal 2D structure and thus the accelerated photogenerated charge separation and transfer process.This work not only provides a novel versatile strategy to design and develop RE-MOFs;but also proposes a promising approach for the potential bulk production of RE-MOFs at room temperature.
