As the area increases, this results in nonuniform preparation of the HTLs, which significantly reduces the efficiency and reliability of the device at the module level. To tackle this significant challenge, we propose a strategy for a dual-fiber network structure based on polymer HTLs. This strategy involves the use of organic solar cell polymer donor material (PM6) and poly(3-hexylthiophene) (P3HT), which are spontaneously interwoven into micron-sized fiber crystals to establish efficient carrier transport channels. This unique structure not only accelerates charge extraction but also takes advantage of the inherent benefits of polymers, such as excellent printability and homogeneous film formation while enhancing the protection of the perovskite layers. The resulting devices demonstrate a VOC of 1.18 V and a champion PCE of 24.90%, which is higher than the pristine devices (the PCE is 22.87%). Moreover, due to the improved printing characteristics, the PSMs prepared by blade-coating also demonstrate a high PCE of 15.15% within an aperture area of 100 cm2. Additionally, this strategy significantly improves the operational stability, thermal stability, and humidity stability of the devices.","PeriodicalId":72127,"journal":{"name":"Aggregate (Hoboken, N.J.)","volume":"6 6","pages":""},"PeriodicalIF":13.9,"publicationDate":"2025-04-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/agt2.70017","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144339491","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Present therapeutic methodologies are characterized by their protracted duration and invasiveness, which often result in suboptimal antibiotic therapy. Consequently, there is an imperative requirement for the development of novel therapeutic approaches for the management of bacterial keratitis. In this study, we present two types of XOFs connected by [N···Br+···N] interactions. These frameworks were characterized using 1H NMR, IR, XPS, SAXS, and HR-TEM. Two-dimensional (2D) structural models were established based on PXRD data and theoretical simulations. The application of these XOFs as novel antibacterial agents for the treatment of bacterial keratitis were explored, and the effects of different connection knots and hydrophilicity on the antibacterial efficacy of XOFs were compared. As expected, the therapeutic effect of XOFs based on [N···Br+···N] interactions are superior to XOFs based on [N···I+···N] interactions. The therapeutic effect of TPPA-based XOFs with good hydrophilicity is better than TPPE-based XOFs. In addition, a photothermal agent (IR820) was loaded onto XOF(Br)-TPPA for combined photothermal and chemotherapy, with experimental results indicating a substantial enhancement in therapeutic efficacy. This work not only deepens our understanding of halogen-bonded organic frameworks but also paves the way for the application of XOFs in biomedical materials.","PeriodicalId":72127,"journal":{"name":"Aggregate (Hoboken, N.J.)","volume":"6 6","pages":""},"PeriodicalIF":13.9,"publicationDate":"2025-04-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/agt2.70050","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144339613","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Organic photothermal CTCs are of particular interest because of their unique phototherapeutic effects in phototherapy and their remarkable imaging capabilities in fluorescence, magnetic resonance, and photoacoustic imaging, further enhancing their significance in medical applications. However, the use of photothermal CTCs in biomedicine has been limited, with few reported biological applications.

The mechanism of nonconventional fluorescence remains incompletely understood, hindering the prediction and modulation of its emission color. Achieving full-color tunability in such systems, particularly within elastomers, is highly challenging. Herein, fluorescent cross-linked polysiloxanes are synthesized using aliphatic amino-terminated polysiloxane and glutaraldehyde, exhibiting full-color emission that can be continuously tuned through thermal treatments within a single material system. Thermal treatment of cross-linked polysiloxanes enables precise control over the structural evolution of fluorophores from imines to 3-(2-piperidyl)pyridinium derivatives and their aggregation states. It enables the continuous and wide-range modulation of the emission color. Additionally, the intramolecular and intermolecular charge transfers of the novel unconventional fluorophore, 3-(2-piperidyl)pyridinium derivatives, have been identified, which are of great significance for aggregation-induced bathochromic fluorescence. Prepared from all commercial chemicals, these cross-linked polysiloxanes show great potential for large-scale production and applications, especially as flexible fluorescent light-conversion layers and solvent-responsive smart materials.

We recently showed the reversible aggregation of gold nanoparticles (AuNPs) via a small, cationic di-arginine peptide; however, the mechanism underlying this aggregation is not yet comprehensively understood. Here, we seek insights into the intermolecular interactions of cationic peptide-induced assembly of citrate-capped AuNPs by empirically measuring how peptide identity impacts AuNP aggregation. We examined the nanoscale interactions between the peptides and the AuNPs via UV-vis spectroscopy to determine the structure-function relationship of peptide length and charge on AuNP aggregation. Careful tuning of the sequence of the di-arginine peptide demonstrated that the mechanism of assembly is driven by a reduction in electrostatic repulsion. We show that acetylated N-terminals and carboxylic acid C-terminals decrease the effectiveness of the peptide in inducing AuNP aggregation. The increase in peptide size through the addition of glycine or proline units hinders aggregation and leads to less redshift. Arginine-based peptides were also found to be more effective in assembling the AuNPs than cysteine-based peptides of equivalent length. We also illustrate that aggregation is independent of peptide stereochemistry. Finally, we demonstrate the modulation of peptide-AuNP behavior through changes to the pH, salt concentration, and temperature. Notably, histidine-based and tyrosine-based peptides could reversibly aggregate the AuNPs in response to the pH.","PeriodicalId":72127,"journal":{"name":"Aggregate (Hoboken, N.J.)","volume":"6 6","pages":""},"PeriodicalIF":13.9,"publicationDate":"2025-04-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/agt2.70043","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144339514","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
