Abstract The self-assemble of flexible ligand 5,5ˊ-(4,4ˊ-phenylenebis(methyleneoxy)) diisophthalic acid (H4L) and N-donor ligands with the different molecular size, 3,3′,5,5′-tetramethyl-4,4′-bipyrazole (bpz) and 1,10-phenanthroline (phen), has generated two new coordination polymers, [Co(L)0.5(bpz)·2.5H2O]n (1) and [Mn(H2L)(phen)]n (2). 1 has a 3D twofold interpenetrated 2-nodal 4,4-c network with a Schlafli symbol of (64.82)(66)2 topology, while 2 exhibits a 2-D grid net, which is further afforded 3D supramolecular motif through π π interactions with 3.65 A between adjacent phen linkers. The influences of various N-donor ligands in assembly of flexible polymers accompany with H4L are also summarized. Photocatalytic studies show that 1 and 2 exhibits efficient degradation activity of organic dye methyl violet (MV). Meanwhile, the possible mechanism of the photocatalytic property has been deduced.
