英文摘要	We have successfully synthesized novel, nickel-based, pillared DABCO-MOFs (DMOFs) of similar topologies - [Ni(L)(DABCO)(0.5)], where L is the functionalized BDC (1,4-benzenedicarboxylic acid) linker and DABCO is 1,4-diazabicyclo[2.2.2]-octane. The stability of DMOF-ADC ([Ni(9,10-anthracenedicarboxylic acid)(DABCO)(0.5)]) and DMOF-TM ([Ni(2,3,5,6-tetramethyl-1,4-benzenedicarboxylic acid)(DABC0)05]) in a humid environment was confirmed by surface area analysis on the water-exposed samples. When used as electrode materials, these DMOF capacitors exhibited excellent electrochemical performance. For example, a Ni-DMOF-ADC electrode showed specific capacitances of 552 and 438 F g(-1) at current densities of 1 and 20 A g(-1), respectively, while maintaining outstanding cycling stability (capacitance retention of > 98% after 16,000 cycles at current density of 10 A g(-1)) for MOF-derived materials based supercapacitors. The excellent electrochemical performance is attributed to the conversion of DMOFs to highly functionalized nickel hydroxide which inherited the high stability of DMOF-ADC and remained intact during charge-discharge process. Further, this work provides a general approach for the application of nickel-based pillared MOFs as relatively stable electrode in electrical energy storage.
