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_(2)O)_(3)]·2H_(2)O}n(1)and{[Co_(3)(μ_(3)-OH)(L)(H_(2)O)]·2DMF·3H_(2)O}n(2)have been successfully prepared by the reaction of Co(NO_(3))_(2)·6H_(2)O withπ-electron-rich polycarboxylate aryl ether ligand 5,5’-((5-carboxy-1,3-phenylene)bis(oxy))diisophthalic acid(H5L)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.
