Their unique morphology arises from a multistep growth process, involving (1) the nucleation of Bi13S18Br2 nanorods, (2) the reduction of a metallic-Bi domain on their surface induced by N,N-didodecylmethylamine, and (3) the heterostructure accretion by a localized reaction at the Bi/Bi13S18Br2 interface promoted by Ostwald ripening. These heterostructures display remarkable stability in polar solvents, remaining almost unaffected by prolonged exposure to isopropanol and water, and exhibit high photocatalytic efficiency for the degradation of organic dyes (i.e., Rhodamine B and Methylene Blue) under visible-light irradiation, with good recyclability. Additionally, preliminary tests demonstrate CO2 reduction capabilities, which make these heterostructures promising for both the photocatalytic degradation of pollutants and photoelectrochemical CO2 conversion. The straightforward synthesis process and the use of nontoxic and Earth-abundant elements offer significant potential for sustainable energy conversion technologies.","PeriodicalId":19,"journal":{"name":"ACS Materials Letters","volume":"7 5","pages":"1707–1716 1707–1716"},"PeriodicalIF":9.6,"publicationDate":"2025-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://pubs.acs.org/doi/epdf/10.1021/acsmaterialslett.5c00043","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143903175","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Herein we report a proof-of-concept strategy employing plastics–fertilizer homology toward this goal. Biomass-like supramolecular plastics were fabricated through solid-phase molecular self-assembly of alginate and alkylammonium surfactants, followed by calcium coordination. The resultant plastics display satisfactory dry and wet mechanical strength, comparable to that of conventional petroleum plastics, while being fully biodegradable. The biodegradation products were able to increase pak choi’s wet/dry weights by 40% and 12%, respectively, promoting both soil fertility and water retention. This natural closed-ring cycle is very similar to real biomass processes, verifying the plastics–fertilizer homology as a promising solution to white pollution and microplastics crises.","PeriodicalId":19,"journal":{"name":"ACS Materials Letters","volume":"7 5","pages":"1646–1653 1646–1653"},"PeriodicalIF":9.6,"publicationDate":"2025-03-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143903228","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Since TTM• is structurally alternant, based on the orbital-pairing features described for alternant hydrocarbons, it was proposed that the D-A• molecule could exhibit emissive properties only when the donor component is nonalternant. This hypothesis seemed to be validated by the synthesis of the alternant TTM•-tetracene system, which was measured to be nonemissive. While some experimental findings have deviated from the alternant rule, the underlying mechanism remains unclear. Here, we investigate quantum mechanically the excited-state properties of a series of TTM•-acene radicals. The results of our high-level calculations highlight that alternant hydrocarbons should not be disregarded in the design of radical emitters, rationalize the absence of emission in TTM•-tetracene, and lead to a set of simple rules to obtain highly luminescent TTM-D emitters.","PeriodicalId":19,"journal":{"name":"ACS Materials Letters","volume":"7 4","pages":"1620–1625 1620–1625"},"PeriodicalIF":9.6,"publicationDate":"2025-03-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143785037","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

By contrast, single-crystal PSCs face unique challenges. Their growth requires pristine, additive-free conditions, and controlling facet passivation remains difficult both during and after crystallization. These limitations primarily manifest as higher trap density at interfaces with charge-transport layers rather than within the crystal bulk. To address this challenge in single-crystal PSCs, we modified the hole-transport layer (HTL) surface by using a hydrophilic dielectric polymer. This treatment prevents charge leakage near pinholes while maintaining the single crystal adhesion. Our champion device achieved a high fill factor of 0.82, a large Voc of 1.08 V, and a record-setting power-conversion efficiency of 25.0% for single-crystal PSCs. Furthermore, the polymer’s hydrophilic properties, combined with strong crystal adhesion, enhanced the device’s operational stability.
