• Recent information has been compiled on the application of MOFs for Li-Batteries applications. • MOFs and their composites have been discussed as a cathode/anode material for various Li-batteries. • Performance of MOF-composites is reviewed in terms of specific capacity and cyclic stability. • MOF and their composites are discussed in detail for Li-HEC in separate section. Metal organic frameworks (MOFs) have emerged as a novel class of advanced functional materials due to their many well-known merits (e.g., ultrahigh porosity, favorable pore size distribution, easy functionalization, and structural tailorability). However, their use in various electronics applications is restricted due to their insulating nature. Therefore, a need arises to intercalate MOFs with various functional/conductive materials for synergistic applications like electrode materials (e.g., diverse Li-ion batteries: LIBs). In this review, the recent developments on pristine MOFs and their derived nanostructures (e.g., nanoporous carbons and metal oxides) for electrode applications are discussed in detail. We focused on the recent applications of various MOF-based composites in anodic/cathodic materials (e.g., LIBs, lithium-sulfur batteries (Li-S), lithium-air batteries (Li-O 2), and lithium hybrid electrochemical capacitors (Li-HEC)) along with details associated with their electrochemical performance. This review is expected to help materials scientists to construct a roadmap for the selection of the best possible electrode materials for LIBs. [ABSTRACT FROM AUTHOR]

Metal-organic frameworks (MOFs) belong to a novel class of materials with several advantages (e.g., ultrahigh porosity, tunable pore size distribution, convenience of synthesis, and structural tailor-ability). However, the insulating nature of MOFs is often recognized as a limiting factor in the extension of their applications, especially in electronic fields. In light of such limitations, various functional or conductive materials have been mixed/intercalated with MOFs to improve their potential for such applications (e.g., rechargeable batteries, optoelectronics, and supercapacitors). Lately, many of these composite materials have been recognized as next-generation electrodes for the development of efficient supercapacitors. In this review article, we have critically reviewed the recent advancements in supercapacitor applications of MOFs and their derived composite structures. Further, we have also discussed the application of various categories of electrolytes (e.g., aqueous, organic, ionic liquids, solid-state, and redox electrolytes) and their impacts on the development of MOF-based supercapacitors.

• Luminescent MOFs and their composites showing great promise in OLEDs. • Application of MOFs is useful to obtain enhanced quantum efficiencies and emission lifetimes. • MOFs offer development of efficient white light emitters. • MOFs in OLEDs provide fairly good CCT and CRI values and wider color emission gamuts. Metal-Organic Frameworks (MOFs) are hybrid organic-inorganic materials with enhanced electronic and optical functionalities that can be tailored by the judicious selection of the building units or their combinations. A large-scale diversity of metal-ligand combinations, along with the ability to form composites, have allowed MOFs to realize enhanced luminescence functionality with applicability in the avenues of solid-state lighting, luminescence-based sensors, and organic light emitting diodes (OLEDs). Because of their enhanced fluorescence lifetimes, high quantum efficiencies, and large-scale tunability, the luminescent MOFs and their composites hold great promise for the OLED industry with enhanced potential to resolve low efficiency issues. The present article presents a comprehensive review of emerging applications for luminescent MOFs and their composites in various OLED applications, with a focus on key attributes like quantum efficiencies, emission lifetimes, tunability, Commission internationale de l'éclairage (CIE) color coordinates, etc. At last, the prospects of luminescent MOFs have been addressed with respect to their future roles and applications in the OLED industry.

[Display omitted] • State of the art information on core–shell MOF-based supercapacitors and batteries are explored. • CSMOF structures are discussed separately in terms of properties, synthesis and their types. • CSMOF structures for supercapacitors are compared in terms of specific capacitance, capacitance retention, energy density, and self-discharge. • CSMOF structures for batteries are compared in terms of reversible capacity, initial discharge capacity, and cyclic stability. • Besides Li-ion batteries, CSMOFs are also reviewed for Na-ion, K-ion, Li-S, Li-Se, and Li-O 2 batteries. • Critical assessment and future aspects are also explored for CSMOF based energy storage devices. Core-shell metal–organic framework (CSMOF) has attracted the attention of researchers in the material science and nanotechnology research field. The structural properties of CSMOF and their derived material include extortionate specific surface area and porosity, good structural flexibility, high stability, etc. These appealing properties make CSMOF a great alternative for various practical applications. CSMOF has shown great performance as an electrode material for energy storage applications. This review is primarily focused on the factor affecting the assemblies and synthesis of core shell structures, strategy to control the assemblies, synthesis methods, and properties of different CSMOFs for energy storage devices viz. supercapacitors (SC) and batteries. After that, different CSMOF structures are compared in terms of their performance parameters for SC including specific capacitance, capacitance retention, cyclic stability, energy density, and self-discharge.On the other hand, reversible capacity, initial discharge capacity, and cyclic stability are a few performance parameters for Li-ion batteries that are also discussed for different materials.CSMOF's applications for some other batteries like Na-ion, K-ion, Li-S, Li-Se, and Li-O 2 will likewise be discussed in other sections. Eventually, the expansion and future scope of CSMOF and its derivatives are proposed for upcoming energy storage applications. [ABSTRACT FROM AUTHOR]
