A four-fold interpenetrated Zn(II)-based coordination polymer with the chemical formula of {[Zn2(L)2(bdc)]·(H2O)2·DMF}n (1) was synthesized by solvent method using terephthalic acid (H2bdc) and N1,N1,N4,N4-tetrakis(4-(1H-imidazol-1-yl)phenyl)benzene-1,4-diamine (L) as the mixed ligands. The as-prepared complex 1 was measured via the elemental analysis and single crystal X-ray diffraction. Furthermore, due to its strong intense emission, complex 1 could be applied as luminescent sensor to sensitively detect 2,4,6-trinitrophenol (TNP), which has the characteristics of high sensitivity and selectivity. In addition, to evaluate the anti-bacterial effect of compound 1 in vitro, the P.gingivalis growth curves were measured. And the relative expression of ragA and ragB was detected by RT-PCR to reveal the mechanism of the compound in the anti-infectious activity. The potential anti-infectious criteria that has been observed in the experimental measurement has been further studied by using molecular docking technique.
