We report here a poly(3,4-ethylenedioxythiophene) (PEDOT) derivative synthesized by the simple and effective addition of thiosulfate pendant groups and illustrate its unique design, with the pendant group separated from the backbone by only one methylene side chain spacer. We establish that the polymer is self-acid-doped and highly water-soluble. In addition, we demonstrate its self-cross-linking functionality, which allows for the fabrication of self-acid-doped films without the need for dopants or other additives. These films were stable in water and retained their electrochemical properties. We therefore present the first example of a thiosulfate group used to self-acid-dope and self-cross-link a PEDOT and showcase an easy methodology for flexible modification of polyelectrolyte side chains.","PeriodicalId":19,"journal":{"name":"ACS Materials Letters","volume":"7 5","pages":"1837–1844 1837–1844"},"PeriodicalIF":9.6,"publicationDate":"2025-04-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143903176","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}

While elucidating the liposome transdermal mechanism, the effects of membrane materials, preparation methods, and various surface modification strategies on liposome transdermal drug delivery systems were further discussed in detail. Furthermore, the article critically points out limitations in liposome transdermal penetration and introduced the penetration-enhancing mechanisms of six different penetration-enhancing technologies, such as microneedle, electroporation, iontophoresis, laser introduction, magnetic introduction, and ultrasonic introduction, along with their specific applications. Finally, the research progress in transdermal treatment has been systematically summarized.

The optimal photodetection system depends on its application, where aspects such as sensitivity, spectral selectivity, noise, and response speed play the critical roles. Perovskite photodetectors, mainly working on photodiodes and photoconductors, have reached great achievements covering a large spectral range from ultraviolet to infrared. To overcome existing limitations in sensitivity, noise, and speed of state-of-the-art systems, advances in device architectures and material strategies are needed. In this Review, we briefly introduce the physical mechanism of phototransistors and discuss recent developments in perovskite phototransistors. We highlight the fundamental trade-offs between parameters for single-material-based devices and clarify how heterostructure devices, consisting of an ultrahigh-mobility channel sensitized with strongly absorbing perovskites, can circumvent these limitations and lead to a next generation of highly sensitive photodetectors. Future directions for their application in high-sensitivity photodetection are proposed.","PeriodicalId":19,"journal":{"name":"ACS Materials Letters","volume":"7 5","pages":"1817–1829 1817–1829"},"PeriodicalIF":9.6,"publicationDate":"2025-04-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143903326","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}

The assembly of Zn(II), chiral auxiliary ligand [(1R,2R)-(+)/(1S,2S)-(−)-1,2-diphenylethylenediamine] (R/S-DPEDA), and fluorescent linkers 2-hydroxyterephthalic acid (HTA) or 2,6-dihydroxyterephthalic acid, affords two pairs of helical CPs, each demonstrating CPL activity with the highest glum and ΦPL reaching up to 0.02 and 40%. The chiral chelate ligands not only orchestrate the self-assembly but also introduce and transfer chirality from the point-chirality of R/S-DPEDA to metal nodes and subsequently to the helical chains, which facilitate the effective integration of fluorescence and chirality, leading to a good CPL performance. By dispersing R/S-DPEDA-HTA into a polydimethylsiloxane matrix, transparent and flexible films with enhanced and inverted CPL are produced.","PeriodicalId":19,"journal":{"name":"ACS Materials Letters","volume":"7 5","pages":"1786–1794 1786–1794"},"PeriodicalIF":9.6,"publicationDate":"2025-04-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143903170","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}

The enhanced ionic conductivity is demonstrated to originate from microstrain-induced crystal lattice expansion. Furthermore, a stable Li+-conductive and intimate interface between halide electrolyte and lithium metal is constructed by introducing a poly(ethylene oxide) protective layer, resulting in the symmetric cell exhibiting a long lifespan with stable cycling over 1000 h at 0.1 mA/cm2 as well as the solid-state lithium metal batteries based on the LiFePO4 cathode reversibly operated for at least 250 cycles at 0.5 C.

Results show that O vacancies significantly alter the catalyst’s surface electronic configuration, optimize the adsorption energy of reactants, lower the reaction energy barrier, and boost POD activity. We synthesized O-vacancy-rich CoFe LDHs quantum dots, verified their excellent catalytic activity, and constructed a sensitive colorimetric detection platform for glucose, glutathione, and nitrite, enabling on-site detection via smartphone integration.

In this context, a heterostructure composed of platinum–tin intermetallic nanoparticles and cobalt nanoclusters, evenly confined in a nitrogen-doped carbon mesh (Pt3Sn/Co@N-CM), is designed that acts as an efficient HER catalyst. Alloying Sn effectively reduces Pt usage and ensures high electrical conductivity during catalysis. Notably, the Co clusters not only accelerate water dissociation in the HER process but also form strong coupling with ordered Pt3Sn particles, thus optimizing the Gibbs free energy for pH-universal HER intermediates. Consequently, Pt3Sn/Co@N-CM attains 10 mA cm–2 current densities at low overpotentials of ∼8, ∼20, and ∼41 mV in acidic, alkaline, and neutral solutions, respectively, outperforming most reported Pt-based counterparts. Additionally, excellent structural and operational stability is achieved, displaying its promising prospects.
