Circularly polarized light, in which the electric field rotates in a circle along the direction of propagation, contains rich optical information and exhibits angle-independent characteristics. This feature makes it widely applicable in asymmetric synthesis, 3D display, and light-emitting devices. Research on circularly polarized luminescence (CPL) has garnered significant attention in recent years. CPL-active materials range from small molecules to supermolecules and from chiral rare-earth complexes to nanosuperstructures. With advancements in developing new materials and technology in chiral science, this field has rapidly developed, and extensive efforts are focused on the development of CPL-active materials with both high photoluminescence quantum yield (PLQY) and large luminescence dissymmetry factor (g_lum). Among these materials, zero-dimensional (0D) chiral hybrid metal halides (CHMHs) characterized by isolated inorganic polyhedra, which combine the chirality of organic cations with excellent photophysical properties of inorganic polyhedra, have emerged as a promising class of CPL-active materials. Despite recent advancements in the design and preparation of CPL-active 0D CHMHs, several challenges remain. Considering the demands of real applications, high PLQY, large g_lum value, and a range of CPL colors are all required.","PeriodicalId":72040,"journal":{"name":"Accounts of materials research","volume":"224 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2025-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143893990","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, its large-scale application is constrained by the high cost, stemming partially from the reliance on noble-metal-based catalysts to enhance the sluggish kinetics of hydrogen and oxygen evolution reactions. To address this challenge, multiscale-coupled heterointerface catalysts (MCHCs), which integrate single atoms, clusters, and nanoparticles into one independent system, have emerged as a potential alternative. They are composed of different active components at multiple scales to achieve strong synergistic effects, where single atoms provide highly active sites with unsaturated coordination environments, clusters enable tunable electronic properties to optimize intermediate binding, and nanoparticles contribute to conductive compensation and robust architecture. Through coupling engineering, these formed heterointerfaces can regulate electronic structures and geometric configurations to break the linear scaling relationship (LSR), simultaneously facilitating H&lt;sub&gt;2&lt;/sub&gt;O activation and intermediate removal. Accordingly, such synergy enables the MCHCs to overcome thermodynamic and kinetic barriers in water electrolysis, significantly boosting the catalytic performance and durability.&lt;/p&gt;&lt;p &gt;Recent progress highlights significant advancements in MCHCs. By precisely tailoring the spatial distribution and interactions of multiscale active components, the MCHCs achieve superior reaction kinetics and long-term durability under harsh conditions of water electrolysis, which address the limitations of conventional single-component catalysts. However, the exact roles of multiscale active sites remain inadequately understood, restricting the ability to fully exploit their synergistic effects. Moreover, some key challenges, including the rational design of heterointerface structures, precise tuning of multicomponent interactions, and the development of advanced characterization techniques to elucidate structure-performance relationships, require more focused investigation. Overcoming these challenges through rational interface engineering and in-depth mechanism studies is crucial for exposing the full potential of MCHCs, which will pave a way for developing high-performance catalysts toward sustainable hydrogen production.&lt;/p&gt;&lt;p &gt;In this Account, we focus on the emerging role of MCHCs, which integrate multiple active sites across different scales to significantly enhance the catalytic performance.
