Abstract

Two Cd(II) coordination polymers (CPs), namely {[Cd(L1)(mip)]·0.33H₂O}_n (1) and {[Cd(L2)(BDC-Cl₄)]·1.35H₂O}_n (2) (H₂mip = 5-methylisophthalic acid; L1 = 1,5-bis(benzimidazol-1-yl)pentane; H₂BDC-Cl₄ = tetrachloroterephthalic acid; L2 = 1,2-bis(2-methylbenzimidazol-1-yl)benzene) were synthesized and characterized. 1 features a 3D pcu network, 2 displays a 2D (4,4) layer. The photocatalytic activities of CPs 1 and 2 for degradation of methylene blue (MB) solution as well as the influence factors such as pH, concentration of dye and catalyst dosage were investigated under UV irradiation. The thermogravimetric analyses and luminescence properties of 1 and 2 were also carried out.

抽象的

两种Cd（II）配位聚合物（CPs），即{[Cd（L1）（mip）]·0.33H ₂ O} _n（1）和{[Cd（L2）（BDC-Cl ₄）]·1.35H ₂ O} _n（2）（H ₂ mip = 5-甲基间苯二甲酸; L1 = 1,5-双（苯并咪唑-1-基）戊烷; H ₂ BDC-Cl ₄ =四氯对苯二甲酸; L2 = 1,2-bis（合成并表征了2-甲基苯并咪唑-1-基）苯）。1具有3D pcu网络，2具有2D（4,4）图层。CP 1和2的光催化活性研究了在紫外线照射下亚甲基蓝（MB）溶液降解的机理以及pH，染料浓度和催化剂用量等影响因素。还进行了1和2的热重分析和发光特性。
