“…1 ). Maintaining anaerobic conditions, within the next defined time interval, the peak was red-shifted and a new band was recorded at 680 nm, assigned to the transition 4 A 2 → 4 T 1 (P) typical for tetrahedral Co(II) complexes [59] , [60] , [61] . In addition, a band at 380 nm appeared, probably related to the CT transition in tetrahedral complexes.…”

“…The peak red-shifts to 541 nm for 1 and 533 nm for 2 upon coordination. A small peak at 823 nm for 1 is ascribed to the d–d transition of Ni(II). , After iodine treatment, the spectra give a broad intense absorption band from 374 to 650 nm for 1-ox and from 374 to 612 nm for 2-ox , with the tail absorption band extending to 1100 nm. The respective direct and indirect band gaps are evaluated using the corresponding Tauc plots (Figure S13).…”

Poor electrical conductivity and instability of metal–organic frameworks (MOFs) have limited their energy storage and conversion efficiency. In this work, we report the application of oxidatively doped tetrathiafulvalene (TTF)-based MOFs for high-performance electrodes in supercapatteries. Two isostructural MOFs, formulated as [M(py-TTF-py)(BPDC)]·2H2O (M = NiII (1), ZnII (2); py-TTF-py = 2,6-bis(4′-pyridyl)TTF; H2BPDC = biphenyl-4,4′-dicarboxylic acid), are crystallographically characterized. The structural analyses show that the two MOFs possess a three-dimensional 8-fold interpenetrating diamond-like topology, which is the first example for TTF-based dual-ligand MOFs. Upon iodine treatment, MOFs 1 and 2 are converted into oxidatively doped 1-ox and 2-ox with high crystallinity. The electrical conductivity of 1-ox and 2-ox is significantly increased by six∼seven orders of magnitude. Benefiting from the unique structure and the pronounced development of electrical conductivity, the specific capacities reach 833.2 and 828.3 C g–1 at a specific current of 1 A g–1 for 1-ox and 2-ox, respectively. When used as a battery-type positrode to assemble a supercapattery, the AC∥1-ox and AC∥2-ox (AC = activated carbon) present an energy density of 90.3 and 83.0 Wh kg–1 at a power density of 1.18 kW kg–1 and great cycling stability with 82% of original capacity and 92% columbic efficiency retention after 10,000 cycles. Ex situ characterization illustrates the ligand-dominated mechanism in the charge/discharge processes. The excellent electrochemical performances of 1-ox and 2-ox are rarely reported for supercapatteries, illustrating that the construction of unique highly dense and robust structures of MOFs followed by postsynthetic oxidative doping is an effective approach to fabricate MOF-based electrode materials.
