With their adjustable structures and diverse functions, polyoxometalate (POM)‐resorcin[4]arene‐based inorganic–organic complexes are a kind of potential multifunctional material. They have potential applications for lithium ion batteries (LIBs). However, the relationship between different coordinated metal ions and electrochemical performance has rarely been investigated. Here, three functionalized POM‐resorcin[4]arene‐based inorganic–organic materials, [Co2(TMR4 A)2(H2O)10][SiW12O40]⋅2 EtOH⋅4.5 H2O (1), [Ni2(TMR4 A)2(H2O)10][SiW12O40]⋅4 EtOH⋅13 H2O (2), and [Zn2(TMR4 A)2(H2O)10][SiW12O40]⋅2 EtOH⋅2 H2O (3), have been synthesized. Furthermore, to enhance the conductivities of these compounds, 1–3 were doped with reduced graphene oxide (RGO) to give composites 1@RGO‐3@RGO, respectively. As anode materials for LIBs, 1@RGO‐3@RGO can deliver very high discharge capacities (1445.9, 1285.0 and 1095.3 mAh g−1, respectively) in the initial run, and show discharge capacities of 898, 665 and 651 mAh g−1, respectively, at a current density of 0.1 A g−1 over 100 runs. More importantly, the discharge capacities of 319, 283 and 329 mAh g−1 were maintained for 1@RGO‐3@RGO even after 400 cycles at large current density (1 A g−1).

“…However, conventional graphite anode shows low-charge storage capacity and unfavorable rate capability, limiting the energy output of LIBs. Polyoxometalates (POMs) are a subset of a multi-electron redox active system, resulting in their great applications, especially energy storage applications. − More importantly, POMs as electrode materials for LIBs have exhibited excellent structural stability, , compared with other anode materials, such as Fe 2 O 3 , CuO, ZnS, and so forth.. − Moreover, to address the inherent drawbacks of bulk POMs, immobilizing POMs on various porous metal–organic frameworks (MOFs) to fabricate compounds (POMOFs) were successively explored and applied in the energy stroage system. − Unfortunately, their performance such as the limited cycling capacity and inferior rate performance is still not satisfactory due probably to the poor conductivity. As a consequence, the integration of POMOFs with conductive carbonaceous materials (e.g., RGO (reduced graphene oxide), , CNTs (carbon nanotubes), , and KB (ketjenblack carbon)) is a promising and efficient strategy.…”

To improve the electrochemical performances and to understand the mechanism of lithium storage of polyoxometalate-based metal–organic frameworks (POMOFs), a generic strategy to construct nanocomposites based on POMOFs and reduced graphene oxide (RGO) assisted by polypyrrole (PPy) as an adhesive, and a conductive additive is demonstrated for the first time in this work. Here, two fascinating vanadium-capped POMs-encapsulating MOFs, [Cu12(Trz)8Cl][PMo12O42V2] (Trz = 1,2,4 triazole) (POMOF-1, and -2), were explored in detail. Although POMOF-1 and -2 have different cell parameters and morphologies caused by the different stacking directions, both are the same compound. Using PPy as an adhesive, POMOF-2 was successfully anchored on RGO, resulting in a new type of POMOF@PPy/RGO (PPG-n, n = 1, 2, 3) nanocomposites. The resulting PPG-3 nanocomposite exhibits excellent reversible capacity (985 mA h g–1 at 50 mA g–1 after 100 cycles) and outstanding rate capabilities, which is much better than those of most nanocomposite electrodes based on POMs. Meanwhile, the lithium storage mechanism of PPG-3 has been discussed by analyzing X-ray photoelectron spectroscopy and powder X-ray diffraction patterns. Moreover, the PPG-3 nanocomposite exhibits the hybrid supercapacitor-battery behavior confirmed by the analysis results of cyclic voltammetry and electrochemical impedance spectroscopy. This might open a new avenue for designing other multifunctional POMOF-based nanocomposites as high-performance electrode materials for lithium storage.

“…In general, both organic ligand and metal centers are important for constructing luminescent coordination polymers. At present, 1,2,4‐triazole derivatives and poly‐carboxylic acid ligands have gained more attention because these functional components can be bridged to formation of coordination compounds with different structural motifs . In addition, aromatic conjugated backbones (such as benzene moieties) also promoted the photoluminescence properties of the coordination polymers.…”
