A water-soluble metallo-supramolecular polymer MSP-f-6Np, which possesses a regular pore aperture of 1.4 nm, has been assembled from a structurally flexible naphthalene-appended [Ru(bipy)3]2+ complex and cucurbit[8]uril. As the first periodic metallo-supramolecular polymer formed by a flexible building block, MSP-f-6Np exhibits a hydrodynamic diameter of 122 and 164 nm at 0.1 and 2.0 mM of the monomer concentrations. Synchrotron small angle X-ray scattering experiments confirm that MSP-f-6Np possesses porosity periodicity in both the solution and solid states. Compared with a control, the new highly ordered porous system displays enhanced photocatalytic activity for the degradation of organic dyes.

来自柔性构件的周期性金属-超分子聚合物:自组装和光催化降解有机染料

具有规则孔径为1.4 nm的水溶性金属超分子聚合物MSP-f-6Np是由结构上柔性的萘基附加的[Ru(bipy)3 ] 2+配合物和葫芦[8]尿素组装而成的。作为由柔性结构单元形成的第一种周期性金属超分子聚合物,MSP-f-6Np在单体浓度为0.1和2.0 mM时显示出122和164 nm的流体动力学直径。同步加速器小角X射线散射实验证实,MSP-f-6Np在溶液和固态均具有孔隙周期性。与对照相比,新的高度有序的多孔体系对有机染料的降解显示出增强的光催化活性。
