High-entropy (HE) design has materialized as a transformative paradigm in Na-based electrochemical energy storage, redefining the conventional boundaries of compositional and structural optimization. This review elucidates the fundamental principles governing configurational entropy, lattice disorder, and their impact on phase stability and ion-transport pathways in HE electrodes and solid-state electrolytes. Comparative analysis with traditional analogues reveals that compositional complexity stabilizes metastable frameworks, mitigates Jahn-Teller distortions, and broadens Na+ diffusion networks via entropy-mediated flattening of the free-energy surface, effectively lowering the energy above the convex hull. A critical examination of synthesis and processing methodologies, from solid-state and wet-chemical routes to high-pressure-field-assisted sintering, underlines the complex interplay of precursor chemistry, configurational homogeneity, and resulting electrochemical behavior. HE strategies across electrodes and interfaces are discussed with emphasis on the synergy of structural resilience, redox reversibility, and interfacial stability. Intrinsic stability aspects, including mechanical, air, and thermal stability, are correlated with compositional tuning. The review further identifies persisting challenges in entropy quantification, synthetic reproducibility, and predictive modeling of ion transport in disordered lattices. Finally, it presents perspectives integrating machine learning, density functional theory, and molecular dynamics within high-throughput frameworks to accelerate discovery and establish design-property correlations in complex chemical spaces.

Since its emergence in the late 1970s, supramolecular chemistry has become a cornerstone of modern chemical science. Defined by the controlled assembly of molecular components through reversible interactions, it encompasses a wide spectrum of forces, among which halogen bonding (XB) has gained prominence as a versatile and directional interaction with unique applications in molecular design and catalysis. This review highlights catalytic systems in which halogen bonding functions either (i) as an activating interaction toward functional groups; (ii) as a promoter of halogen abstraction in organic substrates and metal complexes; or (iii) as a structural element directing the assembly of the catalyst framework. To maintain a focused and critical perspective, only catalytic systems employing 10 mol% of catalyst or less and demonstrating applicability to the synthesis of structurally diverse product arrays are discussed. The review is organized according to the role of the catalyst, providing a coherent framework for understanding how halogen bonding governs activation, selectivity, and molecular organization. Collectively, the studies discussed herein illustrate how halogen bonding has evolved from a supramolecular curiosity into a tool in catalysis, expanding both the conceptual and practical boundaries of modern supramolecular catalysis.

The demand for high-energy-density, safer batteries is increasing in response to evolving technological and societal needs. The conventional anode and cathode chemistries of lithium-ion batteries are approaching their performance limits, underscoring the need for alternative, more robust electrode materials and battery chemistries. Here, this review critically discusses the advancements in the transition metal chalcogenides and their engineered materials as electrodes for Li-ion and next-generation battery chemistries like Na-ion, Li & Na metal, Li-S, Al-ion, Mg-ion, K-ion, and Zn-ion systems. Initially, the fundamental structure, properties, and composition of transition metal chalcogenides is discussed, which strongly lay the foundation to rationally engineer their properties. General synthesis methods followed by engineering strategies to tune the physical, chemical, mechanical, and electrical properties through interlayer, phase, vacancy, dopant, and composites engineering are broadly discussed. Further, the relationship between the engineered transition metal chalcogenides and their charge storage characteristics, and the factors influencing the storage electrochemistry in various batteries, is elaborated. Followingly, the challenges of transition metal chalcogenides as electrodes in diverse batteries and the scope for future improvements are broadly presented. Finally, the discussion on the engineered transition metal chalcogenides' scope towards practicality is thoroughly analyzed.

Molybdenum-polydopamine (Mo-PDA) coordination architectures with hierarchical “flower-like” morphologies have emerged as a versatile class of hybrid nanomaterials that couple molybdenum's redox and coordination chemistry with polydopamine's adhesive, functionalizable polycatechol scaffold. In this critical review, the structural, synthetic, and application-oriented literature is synthesized to identify reproducible structure-property relationships and persistent gaps that limit translation. Prevailing synthesis strategies—including hydrothermal, solvothermal, in-situ polymerization, and green biomimetic routes—are classified and analyzed to elucidate how nucleation and growth variables (precursor stoichiometry, pH, temperature, solvent polarity, and templating agents) deterministically govern hierarchical morphology, porosity, and accessible surface area. Advanced characterization methods that reveal coordination motifs, oxidation states, and pore architecture (electron microscopy, X-ray, and spectroscopies) are evaluated, linking these descriptors to functional metrics. In a comparative assessment of photocatalysis, pollutant adsorption/water purification, and biomedical delivery/antimicrobial applications, reported performance advantages are critically examined in the context of heterogeneous evaluation practices that currently limit cross-study interpretability. Key bottlenecks (including scalability, reproducibility, precise morphological control, and mechanistic insight under operating conditions) are identified, and a guiding framework for the consistent use of application-relevant performance descriptors, together with multi-scale modeling and targeted functionalization strategies, is articulated to support more predictive, design-oriented development. This review aims to move the field beyond largely descriptive reports toward an evidence-informed, application-oriented interpretative framework for Mo-PDA hybrids.

Organic thermoelectric (TE) materials have attracted significant attention because of their mechanical flexibility, lightweight, and large-scale solution processability, resulting in considerable progress over the past 20 years. In this review, we present a comprehensive and timely survey of organic TE materials, focusing on their molecular structure, charge transport mechanisms, and material-level optimization strategies. We further highlight their promising applications, including power generation, active cooling, temperature sensing, and photothermal sensing. Despite these advances, the TE figure of merit (ZT) obtained for organic TE materials still lags behind that of inorganic TE materials. Therefore, this review also critically examines the underlying challenges contributing to the low ZT values in organic systems. Finally, we provide a forward-looking perspective on future research directions to enhance the performance of organic TE materials.

Ether‑oxygen based covalent organic frameworks (EO-COFs) represent an emerging class of porous crystalline materials that uniquely integrate the dynamic flexibility of ether‑oxygen (EO) bonds with the structural order of covalent organic frameworks (COFs). Compared to other COFs, EO-COFs exhibit remarkable structural adaptability, excellent chemical and thermal stability, and versatile post-modification compatibility, owing to tunable conformation and robust electronic nature of the C-O-C linkages. Since their first report in 2015, EO-COFs have demonstrated considerable application potential in multiple fields, including adsorption/separation, catalysis, chemical sensing, and energy storage, etc. These materials not only inherit the flexibility of EO polymers but also significantly enhance the porosity and crystallinity of COFs, thereby expanding their functionality and application scope. However, critical knowledge gaps persist in EO-COFs research, particularly in establishing quantitative structure-performance correlations, innovating low-cost synthetic pathways, and tailoring materials for advanced application fields. Therefore, this review will systematically summarize the preparation methods, properties, and application prospects of EO-COFs and discuss the development opportunities and challenges. We anticipate this review will stimulate more perspectives and new ideas for developing advanced functionalities and expanding regimes of EO-COFs.
