However, traditional macrocycles, such as cyclodextrins, calixarenes, cucurbiturils, and pillararenes, have inherent limitations in terms of cavity size and structural variety, which restrict their ability to encapsulate guest molecules of varying sizes and their potential in constructing multifunctional materials. To address these challenges, our group has developed a simple, universal, and modular strategy for constructing functional macrocycles, termed biphen[<i>n</i>]arenes. This approach leverages structure- or function-oriented modular replacement of reactive, functional, and linking modules. Therefore, biphen[<i>n</i>]arenes with customized cavity size and molecule depth can effectively encapsulate guests from small molecules to biomacromolecules. On the other hand, different from modification of side chains, incorporation of functional primitives into the biphen[<i>n</i>]arene scaffold can leave active sites on both edges to induce additional moieties to improve recognition potency or integrate extra application functionality. These characteristics provide significant advantages in the construction of diverse supramolecular materials.","PeriodicalId":72040,"journal":{"name":"Accounts of materials research","volume":"3 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2025-05-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144114500","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}

The strong quantum size effects and discrete electronic energy levels endow metal nanoclusters with structure-dependent properties, where any perturbation of their compositions or structures induces significant variations in their properties. This makes the research of metal nanoclusters particularly exciting but also challenging, as small changes in their atomic composition or arrangement can result in substantial differences in their behavior. As a result, the study of metal nanoclusters follows a node-style research pattern, wherein major breakthroughs often lead to new insights into their structural and functional properties. However, despite these advances, the systematic exploration of these materials remains highly challenging. In recent years, there has been increasing interest in the development of unified theoretical models that can predict and control the properties of metal nanoclusters, potentially making them ideal candidates for programmable nanomaterials. Key examples of well-studied nanoclusters include Au₂₅(SR)₁₈ and Ag₄₄(SR)₃₀, which have provided valuable insights into the fundamental principles of metal nanocluster chemistry. Nevertheless, given the vast differences observed among various cluster frameworks, there is an urgent need to develop new models and explore versatile approaches for the preparation of nanoclusters with tunable functionalities.

Colloidal semiconductor nanocrystals (NCs), known as quantum dots (QDs), have attracted increased attention for a wide range of potential applications, such as displays, lighting, photovoltaics, and biological imaging, because of their high quality and size-dependent optical properties. To obtain high-quality semiconductor NCs with reduced surface defects and boosted photoluminescence emission, semiconductor shell-based surface engineering is a commonly used strategy. However, the terminated semiconductor surface is likely not immune to photodegradation or chemical degradation behavior. Insulating matrix encapsulation was demonstrated to be an alternative way to resolve the stability issue, but the bulk and insulating feature of the matrix could restrain the electrical activity and solution processability for device applications of NCs. As a compromise, the chemically inert atomic passivation shell (CIAPS) could be the ideal approach to break the above-mentioned trade-off and promote practical optoelectronic applications. The CIAPS on semiconductor NCs can protect the NCs from the surrounding environment physically and isolate photogenerated excitons from the external photochemical reactions while maintaining access to charge injection or transport for device applications.","PeriodicalId":72040,"journal":{"name":"Accounts of materials research","volume":"41 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2025-05-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144087962","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}

Morhenn, Michael Keis","doi":"10.1021/accountsmr.5c00053","DOIUrl":"https://doi.org/10.1021/accountsmr.5c00053","url":null,"abstract":"Organic battery electrode materials are key enablers of different postlithium cell chemistries. As a p-type compound with up to two reversible redox processes at relatively high potentials of 3.5 and 4.1 V vs. Li/Li&lt;sup&gt;+&lt;/sup&gt;, phenothiazine is an excellently suited redox-active group. It can easily be functionalized and incorporated into polymeric structures, a prerequisite to obtain insolubility in liquid battery electrolytes. Phenothiazine tends to exhibit π-interactions (π*−π*-interactions) to stabilize its radical cationic form, which can increase the stability of the oxidized form but can also strongly influence its cycling performance as a battery electrode material. In recent years, we investigated a broad range of phenothiazine-based polymers as battery electrode materials, providing insight into the effect of π-interactions on battery performance, leading to design principles for highly functional phenothiazine-based polymers, and enabling the investigation of full cells. We observed that π-interactions are particularly expressed in “mono”-oxidized forms of poly(3-vinyl-&lt;i&gt;N&lt;/i&gt;-methylphenothiazine) (PVMPT) and are enabled in the battery electrode due to the solubility of oxidized PVMPT in many carbonate-based liquid electrolytes. PVMPT dissolves during charge and is redeposited during discharge as a stable film on the positive electrode, however, still retaining half of its charge. This diminishes its available specific capacity to half of the theoretical value. We followed three different strategies to mitigate dissolution and inhibit the formation of π-interactions in order to access the full specific capacity for the one-electron process: Adjusting the electrolyte composition (type and ratio of cyclic vs. linear carbonate), encapsulating PVMPT in highly porous conductive carbons or cross-linking the polymer to X-PVMPT. All three strategies are excellently suited to pursue full-cell concepts using PVMPT or X-PVMPT as positive electrode material. The extent of π-interactions could also be modified by structural changes regarding the polymer backbone (polystyrene or polynorbornene) or exchanging the heteroatom sulfur in phenothiazine by oxygen in phenoxazine. By changing the molecular design and attaching electron-donating methoxy groups to the phenothiazine units, its second redox process can be reversibly enabled, even in carbonate-based electrolytes. Studies by us as well as others provided a selection of high-performing phenothiazine polymers. Their applicability was demonstrated as positive electrode in full cells of different configurations, including dual-ion battery cells using an inorganic or organic negative electrode, anion-rocking-chair cells as examples of all-organic batteries, or even an aluminum battery with a performance exceeding that of aluminum-graphite battery cells. In changing the design concept to conjugated phenothiazine polymers, a higher intrinsic semiconductivity can result, enabling the use of a lesser amo","PeriodicalId":72040,"journal":{"name":"Accounts of materials research","volume":"58 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2025-05-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144087959","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}

They exhibit unique physical, chemical, and electronic properties, making 2D materials highly promising in the fields of sustainable energy storage and electrocatalysis. Although significant progress has been made in the design and performance optimization of 2D materials, challenges persist, particularly in energy storage and electrocatalysis. A key issue is the restacking or aggregation of these materials in the powder form, which hinders ion transport and reduces their overall performance by limiting the effective surface area. In this Account, we delve into the latest advancements made by our team in the chemistry of 2D materials toward sustainable electrochemical energy storage and catalysis. We begin by highlighting some of the representative 2D materials developed by our team, such as fluorine-modified graphene and transition metal telluride nanosheets. These materials, with their atomic-scale thickness, offer significant advantages over traditional bulk materials by circumventing issues such as limited active surface area, extended ion transport pathways, and complex manufacturing processes, thereby providing innovative approaches for the development of high-performance materials. Next, the key synthesis strategies that have been pivotal in our research are summarized. Techniques such as electrochemical exfoliation, solid-state lithiation and exfoliation, and ion-adsorption chemical strategies have enabled precise control over the ionic and electronic conductivities, lateral dimensions, and internal atomic configurations of 2D materials. These methodologies not only facilitate the preparation of 2D materials with tailored properties, but also support the scalable production of high-quality materials. Furthermore, we outline the broad applications of 2D energy materials across various domains. In alkali-based batteries, these materials have been instrumental in enhancing battery performance, including extending the cycle life and improving the charge–discharge efficiency. They also contribute to increased energy and power densities in aqueous-based batteries and supercapacitor–battery hybrid devices. In the realm of metal-free anodes, they play a crucial role in inhibiting metal dendrite growth, thereby enhancing battery safety. Additionally, in energy catalysis, they demonstrate superior catalytic activity, promoting efficient energy conversion. In microscale electrochemical energy storage devices, they meet the demands for high power and energy density, propelling the advancement of miniaturized energy storage solutions. Lastly, we address the critical challenges confronting 2D energy materials and offer a perspective on future directions.

The reactions are typically affected by the low gas solubility in liquids and poor mass transfer from the gas phase to the liquid, especially for fast reactions, leading to much lower activity than the intrinsic catalytic activity. In practice, high pressure, temperature, and cosolvents are required to increase the gas solubility and boost the reaction rate. Gas–liquid–solid (G-L-S) microreactors based on particle-stabilized (Pickering) foams rather than conventional surfactant-stabilized foams can increase the contact between the gas and liquid phases, together with surface-active catalytic particles, and dramatically accelerate G-L-S reactions. Unlike surfactants, surface-active catalytic particles can be recycled and reused and reduce coalescence, Ostwald ripening, and aggregation by adsorbing selectively at the G-L interface, promoting stability.","PeriodicalId":72040,"journal":{"name":"Accounts of materials research","volume":"29 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2025-05-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143930641","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}
