合成了层状结构的MOF[Ni(Hppza)(2)](N)(1)，并用单晶X射线衍射、元素分析和红外光谱对其进行了表征。对于配合物1，晶体结构通过N-H中心点O氢键扩展为三维结构。这是第一次，这种络合物被用作超级电容器的电极材料。当放电电压为5 mV S(-1)时，其比电容可达184Fg(-1)。这一数值显示了目前超级电容器中所有MOF材料的最佳性能。这种优异的电化学性能可以归因于Ni-MOF材料的固有特性，包括其晶体结构和形貌。
A layered structural MOF [Ni(Hppza)(2)](n) (1) was synthesized and characterized by single-crystal X-ray diffraction, elemental analyses and IR spectroscopy. For complex 1, the crystal structure is extended into 3D structure through N-H center dot center dot center dot O hydrogen bond. And for the first time, this complex used as an electrode material for a supercapacitor. It exhibited large specific capacitance of 184 F g(-1) can be achieved at rates of 5 mV s(-1). The value demonstrated the best performance of all the MOF materials in supercapacitor at present. Such an excellent electrochemical property may be attributed to the intrinsic characteristics of Ni-MOF material including its crystal structure and morphology.
