Abstract
By changing the solvents, three polyoxometalate (POM)-based supramolecular hybrids, [Co2L3][SiW12O40]·17H2O (1), [Co2L2(H2O)4][SiW12O40]·2EtOH·2H2O (2) and [Co2L3][SiW12O40]·9DMA·6H2O (3), have been synthesized under hydrothermal or solvothermal conditions. All three hybrids show various supramolecular structures, which contain two kinds of different metal-organic motifs. A kind of metal-organic cationic cage [Co2L3]4+ is formed in the presence of H2O for 1, DMA/H2O for 3, and a metal-organic cationic circle [Co2L2]4+ is constructed in the presence of EtOH/H2O for 2. That is to say, the solvents show a key role in tuning the architectures of metal-organic fragments and the final POM-based supramolecular structures. The adsorption properties of 1–3 for different organic dyes have also been investigated.
