Abstract A new coordination polymer with the chemical formula of [Co2(TIPA)(HCOO) (NDC)1.5]·4DMF·CH3OH·2H2O (1) has been successfully prepared by using naphthalene-2,6-dicarboxylic acid (H2NDC) and tris(4-(1H-imidazol-1-yl)phenyl)amine (TIPA) as coordination ligands and a mixed solvent of water, MeOH and DMF as the solvent system. Complex 1 shows light adsorption in the visible region because of the charge transition from ligand to the metal, which could be used for visible light degradation of rhodamine B and methylene blue with highly photocatalytic efficiency. Furthermore, the mechanism of photocatalysis was hypothesized and verified in detail by the reaction of photocatalysis in the existence of mannitol, a hydroxyl radical scavenger, and 1,4-benzoic acid, a collector. Furthermore, the treatment activity of the compound against pelvic inflammatory disease (PID) was evaluated in this research. The MBC of the compound against Uu was measured in vitro. In addition to this, the ELISA detection of IL-1β and IL-6 also measured to evaluate the anti-inflammatory effect of the compound on PID. Keywords Co(ii)-framework · Photocatalytic degradation · Pelvic inflammatory disease
Introduction Pelvic inflammatory disease (PID) means severe inflammation of genital genitalia and surrounding tissues of the female pelvic peritoneum [1]. PID is a common gynecological clinical disease with high incidence. It has the character of recurrent episodes, long-lasting disease course, unstable treatment effect, and it is easy to cause complications such as ectopic pregnancy, infertility or neurosis, which brings a series of problems to patients’ psychology and family [2, 3]. Ureaplasma urealyticum (Uu) is one of the common bacteria leading to the production of PID [4]. Thus, in this article, we aimed to develop the new candidates for the treatment of PID via killing Uu.

Coordination polymers (CPs) have been widely concerned not only because of their unique topology and structure, but also because of they have latent applications in gas separation and adsorption, electrical conductivity, magnetic, heterogeneous catalysis and biomedicine [5–10]. The final properties of CPs are affected by a lot of factors, including the properties of the metal ions, charge balance ions, organic ligands, the ratio of ligand and metal, solvents cocrystallization as well as coordination [11–13]. Therefore, using suitable factors to design and build CPs which have ideal performances ha
