中文摘要:
      采用水热法合成了含混合配体的铜配合物[CuLPhen]n(HL=5-硝基间苯二甲酸,Phen=1,10-菲咯啉),其结构由单晶X射线晶体学确定。标题化合物在单斜空间群P21/c中结晶。标题化合物的晶体数据:C20H11N3CuO6,Mr=106.57,a =10.6619(3),b =12.5760(4),c =13.0550(3)Å,α =90,β=95.463(3),γ =90°,V =1742.50(9)Å3Z =4,T=293(2)K,Dc =1.726 g/cm3μ(MoKα)=0.301 mm-1F(000)=51.0,R =0.0380,wR =0.07,GOF =1.026。当用作超级电容器电极材料时,所制备的配合物具有高比电容、良好的循环稳定性和优良的倍率性能。具体来说,在1 mol/L KOH溶液中,最大比电容可达到225 F/g。在5 a/g电流密度下,5000次循环后比电容保持率为67.31%。
英文摘要:
      A copper complex with mixed ligands, [CuLPhen]n (HL = 5-Nitro-isophthalic acid, Phen = 1,10-phenanthroline) was synthesized by a hydrothermal approach and its structure was determined by single-crystal X-ray crystallography. The title complex crystallizes in monoclinic space group P21/c with the crystal data: C20H11N3CuO6, Mr = 106.57, a = 10.6619(3), b = 12.5760(4), c = 13.0550(3) Å, α = 90, β = 95.463(3), γ = 90°, V = 1742.50(9) Å3, Z = 4, T = 293(2) K, Dc = 1.726 g/cm3, μ(Mo) = 0.301 mm-1, F(000) = 51.0, R = 0.0380, wR = 0.0907, and GOF = 1.026. When used as electrode materials of super-capacitor, the prepared complex showed high specific capacitance, good cycle stability and excellent rate performance. Specifically, the maximum specific capacitance could achieve 225 F/g in 1 mol/L KOH solution. At the current density of 5 A/g, the retention of specific capacitance was 67.31% after 5000 cycles.
