“…Co-MOF, Ni-MOF, and Co 2.75 Ni 1 -MOF also exhibit a broad absorption band from 200 to 375 nm due to the π–π* transition of the ligands. However, their absorption bands present some red shifts compared with those of the ligands, which may be due to the charge-migration transition of the ligand to the central metal (LMCT). , Moreover, Co-MOF has a wide absorption peak centered at 535 nm belonging to the d → d transition with 4 A 2 (F) → 4 T 2 (P) for the central Co(II) ion of the d 7 configuration . The strong absorption peak at 662 nm of Ni-MOF is attributed to the d → d transition with [ 3 T 1g (F) → 3 A 2g ] .…”

Two new metal–organic frameworks (MOFs), [Co(bcpp)(bbip)]·H2O (Co-MOF) and [Ni(bcpp)(bbip)]·H2O (Ni-MOF), have been generated based on a V-type flexible carboxylic ligand 3,5-bis(4-carboxyl phenoxy) pyridine (H2bcpp) and a rigid N-donor ligand 1,1′-(1,4-phenylene)bis(1H-benzimidazole) (bbip) by a solvothermal method. Co-MOF and Ni-MOF are isostructural with a 2-fold interpenetrated layered structure. Moreover, a series of bimetallic Co x Ni y -MOFs (x/y = 1:1, 2.5:1, 2.75:1, 3:1, 3.25:1, and 3.5:1) were obtained by using one-pot synthesis. Owing to their mixed metallic components and internal layered structure, the bimetallic Co x Ni y -MOFs possess a remarkable electrochemical storage property. Significantly, the Co2.75Ni1-MOF has high specific capacitance (699 F g–1) at 0.5 A g–1 and good cycling durability (retained 72.7% over 3100 turns). Additionally, an asymmetrical ultra-capacitor based on Co2.75Ni1-MOF and activated carbon (AC) delivers a maximum energy density of 20.44 Wh kg–1 at 387.49 W kg–1 and a high cycle-to-cycle stability with 85.4% of the primary capacitance over 15,000 turns.
