Through precisely adjusting the pH value of reaction system, two new mixed-ligand based coordination polymers, namely [Zn(ip)0.5(bta)]n (1) and [Zn3(Hip)4(bta)2]n (2) (H2ip = isophthalic acid, Hbta = benzotriazole), have been acquired through the self-assemble reaction of Zn(II) salts in combination with H2ip and Hbta. Both compounds have high thermal stability demonstrated by the thermogravimetric analysis (TGA) experiments, and exhibit strong luminescence emission at room temperature. Their application values on the children bone growth and development were evaluated and the specific mechanism was examined simultaneously. Above all, compound 1 was more outstanding than compound 2 against the children bone growth and development by regulating the Vitamin K receptor on the bone cell surface.
