| 摘 要： | In the present study, two new Co(Ⅱ)-based coordination polymers(CPs) with chemical formulas of {Co_3(μ_3-OH)(L)(H_2O)_3]·2H_2O}_n(1) and {Co_3(μ_3-OH)(L)(H_2O)]·_2DMF·3H_2O}_n(2) have been successfully prepared by the reaction of Co(NO_3)_2·6H_2O with π-electron-rich polycarboxylate aryl ether ligand 5,5'-((5-carboxy-1,3-phenylene)bis(oxy))diisophthalic acid(H_5L) under different solvothermal reaction conditions. Both CPs have been studied via single-crystal X-day diffraction, powder X-ray diffraction(PXRD) and thermogravimetric analysis(TGA). The photophysical studies indicated that complex 2 with good water stability is a potential semiconductive material, which could be applied for the degradation of methylene blue(MB) under UV light irradiation and exhibit good stability and recyclability.
