Popis: | Under solvothermal conditions, the reactions of CoII/ZnII ions with bent ligand 3-(pyridin-4-yl)-5-(pyrazin-2-yl)-1H-1,2,4-triazole (4-Hpzpt) afford two compounds {[M(4-pzpt)2] guest}n (guest=H2O, M=CoII (1), ZnII (2)). Both compounds are the thermally and hydrolytically robust 4-connected 3D NbO framework, which formed by double helical chains to give rise to 1D hollow nanochannel with uncoordinated nitrogens completely exposed on the pore surface. Compound 1 exhibits improved N2, CO2 and H2 uptake capacities, while compound 2 displays the strong luminescent emission with obvious red shift. |
