In this study, a new two-dimensional CoII-containing coordination polymer [Co(pda)(H2O)](DMF)2 (1, DMF=N,N-dimethylformamide) based on a light-harvesting triphenylamine type organic ligand has been successfully prepared by reaction of Co(NO3)2⋯6H2O and 4,4′-(phenylazanediyl)dibenzoic acid (H2pda) in a mixed solvent of water and DMF. Complex 1 has significant photocatalytic activity under visible light for the degradation of organic dyes such as rhodamine B (RhB), methylene blue (MB), as well as methyl orange (MO) assisted by H2O2. Compound 1 was investigated for anti-osteoporosis activity, the Annexin V-FITC/PI method was used to test the relationship between apoptosis and osteoporosis and the effect of 1 on bone marrow stem cell (BMSC) apoptosis. The expression levels of wnt/β, catenin, and PPARγ after treatment with 1 was determined by reverse transcription quantitative polymerase chain reaction. The DNA cleavage ability of 1 was further studied by molecular docking.

Naphthalenediimides, a class of organic dyes with an expanded π-electron-deficient plane, have attracted considerable interest because of their photoinduced electron transfer from neutral organic moieties to stable anionic radicals. This makes them excellent candidates for organic linkers in the construction of photochromic coordination polymers. Such a photochromic two-dimensional coordination polymer has been prepared using N,N′-bis(pyridin-4-ylmethyl)naphthalene-1,8:4,5-bis(dicarboximide) (DPMNI). In crystallization tubes, upon slow diffusion of an MeOH solution of cadmium perchlorate into a CHCl3 solution of DPMNI, the complex poly[[bis[μ2-2,7-bis(pyridin-4-ylmethyl)benzo[imn][3,8]phenanthroline-1,3,6,8(2H,7H)-tetrone-κ2 N:N′]bis(perchlorato-κO)cadmium(II)] chloroform tetrasolvate], {[Cd(C26H16N4O4)2(ClO4)2]·4CHCl3} n , (I), was obtained. The asymmetric unit contains one Cd2+ cation, two DPMNI ligands, two coordinated ClO4 − anions and four CHCl3 solvent molecules. Each Cd2+ cation is interconnected by four DPMNI linkers to generate a neutral two-dimensional naphthalenediimide coordination network with all the ClO4 − anions above or below this plane. Strong interlaminar anion–π interactions between the coordinated ClO4 − anions and the imide rings of an adjacent layer lead to a three-dimensional supramolecular structure. Compound (I) exhibits reversible photochromic behaviour and photocontrolled tunable luminescence properties, which may originate from the photoinduced electron-transfer generation of radicals in the DPMNI ligand.

In poly[[μ3-2,2′-(disulfanediyl)dibenzoato-κ5 O:O,O′:O′′,O′′′](1,10-phenanthroline-κ2 N,N′)cadmium(II)], [Cd(C14H8O4S2)(C12H8N2)] n , the asymmetric unit contains one CdII cation, one 2,2′-(disulfanediyl)dibenzoate anion (denoted dtdb2−) and one 1,10-phenanthroline ligand (denoted phen). Each CdII centre is seven-coordinated by five O atoms of bridging/chelating carboxylate groups from three dtdb2− ligands and by two N atoms from one phen ligand, forming a distorted pentagonal–bipyramidal geometry. The CdII cations are bridged by dtdb2− anions to give a two-dimensional (4,4) layer. The layers are stacked to generate a three-dimensional supramolecular architecture via a combination of aromatic C—H...π and π–π interactions. The thermogravimetric and luminescence properties of this compound were also investigated.
