摘要

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.
