However, examples involving photocatalytic reactions to synthesize covalent organic frameworks (COFs) have been rarely reported thus far. Herein, we report for the first time the photocatalytic synthesis of a series of quinoline-linked COFs with high crystallinity and permanent porosity via the photocatalytic three-component one-pot Povarov reaction between different aldehydes, amines, and phenyl vinyl sulfone. Furthermore, the obtained quinoline-linked COFs are stable and can be employed as efficient photocatalysts to promote the photocatalytic oxidative hydroxylation of arylboronic acids to phenols in excellent yields. This photocatalytic polymerization strategy opens a new avenue for the construction of stable quinoline-linked COFs in a green and facile way.","PeriodicalId":19,"journal":{"name":"ACS Materials Letters","volume":null,"pages":null},"PeriodicalIF":9.6,"publicationDate":"2024-10-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142571036","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}

Silver telluride (Ag2Te) colloidal quantum dots (CQDs) can be a promising alternative to traditional Pb- or Cd-based narrow-band gap semiconductors due to their low toxicity. However, the strong binding affinity of thiol ligands has limited the broader use of Ag2Te CQDs, necessitating more versatile surface chemistries. Here, we synthesized Ag2Te CQDs passivated with oleylamine, which facilitated various ligand passivation strategies. The weak bonding strength allows the preparation of X-Ag2Te CQD (X = Cl, Br, or I ligands) inks, sensitive to 1.1–2.7 μm infrared radiation. Using the CQD inks, we fabricated extended short-wavelength infrared (eSWIR) CQD photodiodes with two different sizes of CQDs. The resulting Ag2Te CQD ink-based eSWIR photodiodes exhibited an external quantum efficiency of 16% at 1.7 μm at room temperature, representing the highest value achieved for nontoxic CQD IR detectors at the wavelength.","PeriodicalId":19,"journal":{"name":"ACS Materials Letters","volume":null,"pages":null},"PeriodicalIF":9.6,"publicationDate":"2024-10-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142571033","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}

Additionally, the use of concentrated proteins prevents interpenetration between the backing layer and the tip, assuring the dosage accuracy of the therapeutic antibodies. Physicochemical characteristics, including mechanical strength, dissolvability, and skin permeability, were evaluated and compared with conventional PVP K17 (poly(vinylpyrrolidone), K17) microneedles. Finally, the transdermal performance of protein dMNs was assessed using IL-17A (Iinterleukin-17A) antibody as a model protein drug, with in vivo therapeutic efficacy evaluated in a psoriatic mouse model.

Herein, we develop and validate a smart pH-responsive polymeric microneedle (proT-patch) for efficient drug delivery to the basal epidermal layer of the skin. The microneedle base offers high stiffness, while a variable needle height design eludes the “bed of nails” effect. With its stimuli-responsiveness, the microneedle coating enables drug release under specific pH conditions, enhancing dosage accuracy and minimizing biowaste. The performance of proT-patch is validated using ex vivo human skin by delivering Wnt5a, which switches on Keratin-9 expression, and is not expressed in nonplantar skin. Administering Wnt5a-loaded proT-patch to skin enhanced Keratin-9 expression in basal epidermal keratinocytes compared to topical and unloaded controls. With its facile fabrication, versatility, and exceptional performance, proT-patch shows immense potential as a next-generation, noninvasive tool for therapeutics, cosmetics, and vaccine delivery.","PeriodicalId":19,"journal":{"name":"ACS Materials Letters","volume":null,"pages":null},"PeriodicalIF":9.6,"publicationDate":"2024-10-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://pubs.acs.org/doi/epdf/10.1021/acsmaterialslett.4c01609","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142571110","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}

Compared with other molecular sieving materials, the adsorption capacity of n-C4H8 created a new benchmark (64.27, 54.82, and 0.01 bar). In situ single-crystal X-ray diffraction (SCXRD) and computational simulation validated the vital role of window-specific shrinkage and object adaptation of CALF-20 for high-efficiency molecular sieving and enhancing the n-C4H8 binding interaction. Breakthrough experiments under dry and humid circumstances proved that CALF-20 can achieve efficiently purified i-C4H8 (≥99.999%) with a benchmark productivity of 105 L/kg by one-step adsorption from a n-C4H8/i-C4H8 (50/50, v/v) mixture.
