Since redox-active based supercapacitors are known as highly desirable next generation of supercapacitor electrodes, target design of two same ferrocene-functionalized (Fc(COOH) 2 ) clusters based on coinage metals perform ([(PPh 3 ) 2 AgO 2 CFcCO 2 Ag(PPh 3 ) 2 ] 2 . 7CH 3 OH (SC 1: super capacitor)) and ([(PPh 3 ) 3 CuO 2 CFcCO 2 Cu(PPh 3 ) 3 ]. 3CH 3 OH (SC 2 )). Both structures fully characterize by various analyzes. The structures utilize as energy storage electrode materials and 130 Fg -1 and 210 Fg -1 specific capacitance obtain at 1.5 Ag -1 in Na 2 SO 4 electrolyte, respectively. The obtained results show that the presence of Cu(I) instead of Ag(I) improves the supercapacitive performance of the cluster. Further, to improve the conductivity, the PSC 2 ([(PPh 3 ) 2 CuO 2 CFcCO 2 ] ∞ ) as the polymeric structure of SC 2 synthesizes and use as an energy storage electrode. The PSC 2 displays high conductivity and 455 Fg -1 capacitance at 3 Ag -1 . The PSC 2 as supercapacitor electrode presents high power density (2416 W kg -1 ), high energy density (161 Wh kg -1 ), and long cycle life over 4000 cycles (93%). The results can lead to the amplification of high-performance supercapacitors in new horizons to develop real applications and stimulate the usage of target designed coordination polymer without hybridization or composition with additive materials.
