摘要
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.
