Existing PDLC infrared-responsive strategies usually rely on spatially fixed photothermal absorbers, which restrict switching of encrypted information, limit coding complexity, and introduce readout delays due to thermal inertia. Here, a PDLC platform doped with upconversion particles and fluorescent dyes that supports information switching with immediate responses under infrared (IR) and ultraviolet (UV) illumination is reported. Invisible light responsiveness was achieved and the contrast ratio of the PDLCs increased to 137.06 by tuning the content of the fluorinated monomer TFEMA together with the dopant loading. Integration with laser etched electrodes yielded a multi-responsive device combining UV/IR/alternating-current control. Electric field enabled switching among multiple pattern states, while irradiation at 365 and 980 nm modulated the multistate color output. The electrical and optical driven channels remained independent and orthogonal, which markedly expanded the encoding capacity. The device eliminates reliance on IR absorbers and heat accumulation, establishing a general route to low-latency, high-complexity encryption and enabling rapid, switchable, secure anti-counterfeiting authentication.","PeriodicalId":84,"journal":{"name":"Journal of Materials Chemistry C","volume":" 23","pages":" 10240-10250"},"PeriodicalIF":5.1,"publicationDate":"2026-04-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148261496","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A new type of nontoxic low-cost strain sensor is reported here, whose fluorescence intensity is instantly responsive to the external strain applied over a large range (up to 250% strain). Highly stretchable fluorescent composites of carbon dots (CDs) and polyurethane (PU) are fabricated via a scalable green chemistry method by conveniently dispersing CDs in the aqueous solution of PU. It is discovered that, upon tensile deformation, the fluorescence peak of the CD–PU film remains non-shifted but displays enhanced fluorescence intensity. The observed fluorescence responses to strain are ascribed to the enlarged inter-particle distance of CDs along the tensile direction, although a higher degree of aggregation results from the other two axes. The fluorescence-dependence on the anisotropic patterns of CDs in the solid state points to a new mechanism to overcome aggregation-induced quenching by controlling the distribution behaviors of the fluorescent species.","PeriodicalId":84,"journal":{"name":"Journal of Materials Chemistry C","volume":" 24","pages":" 10833-10840"},"PeriodicalIF":5.1,"publicationDate":"2026-04-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148314702","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Traditional cryptographic materials, constrained by their single-response mode, limited information capacity, and inadequate anti-counterfeiting levels, fail to meet the demands of high-security applications. Here, we introduce cholesteric liquid crystal microcapsules (CLCMs) with triple response capability to temperature, UV light, and blue light, enabling dynamic dual-mode tuning of both structural and fluorescence colors. Featuring a core–shell architecture with a polymethyl methacrylate shell and a spiropyran/boron-dipyrromethene co-doped cholesteric liquid crystal core, these CLCMs exhibit exceptional optical properties. The co-doping enables precise control over photochromic and fluorogenic behaviors, while the shell ensures mechanical stability. Within the temperature range of 8–32 °C, the CLCMs display distinct structural colors spanning red, green, and blue. Under UV light exposure, they achieve a rapid green-to-red fluorescence color shift within 2 seconds, while maintaining stable green fluorescence under blue light illumination with minimal temperature interference. A high-capacity visual encryption strategy maps seven colors to digits, enabling the encoding of all 95 displayable ASCII characters. Each unit supports 514 425 theoretical variants, offering unprecedented information density for secure data storage and authentication. This platform holds transformative potential for secure data storage, anti-counterfeiting, and real-time authentication in high-value applications such as financial documents and medical records.","PeriodicalId":84,"journal":{"name":"Journal of Materials Chemistry C","volume":" 24","pages":" 10854-10863"},"PeriodicalIF":5.1,"publicationDate":"2026-04-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148314704","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Metal–organic frameworks (MOFs) are crystalline porous materials with key physicochemical properties, including adjustable pore size, chiral coordination structures, surface charge, and optical and magnetic properties. In recent years, they have attracted considerable research interest in the context of neurodegenerative diseases due to their potential to influence diagnostic and therapeutic functions. This review provides a comprehensive evaluation of recent progress in the identification of critical biomarkers for neurodegenerative diseases using MOF-based electrochemical and fluorescent sensors. It focuses on the application of MOFs as drug delivery systems, enzyme immobilisation platforms, and nanomedicines in therapeutic interventions and drug development. The review also discusses the challenges and future prospects of using MOFs to construct integrated diagnostic and therapeutic platforms and to advance clinical translation.","PeriodicalId":84,"journal":{"name":"Journal of Materials Chemistry C","volume":" 19","pages":" 7952-7966"},"PeriodicalIF":5.1,"publicationDate":"2026-04-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147978719","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

While aerogels are promising due to their low density and dielectric constant, conventional polyimide (PI) aerogels suffer from high thermal expansion (CTE) and poor moisture resistance, resulting in interfacial delamination and dielectric instability. To address these challenges, octa-amino POSS (OAPS) was introduced as a crosslinking agent into the BPDA/PDA framework, fabricating a series of PI/OAPS hybrid aerogels. In this work, PI/OAPS aerogels with OAPS content ranging from 0.222% to 0.641% were prepared and showed excellent dielectric properties. Particularly at a content of 0.641% (corresponding to 20 repeating units), the aerogel achieved the lowest dielectric constant (Dk, 1.08 at 10.1 GHz) and dielectric loss (0.0013 at 10.1 GHz), which were reduced by 12.6% and 59.0%, respectively, compared with the unmodified aerogel. Furthermore, after the introduction of the OAPS, the contact angle of the PI/OAPS aerogel increased from 88° to 120°, and its coefficient of CTE was reduced to 16.7 ppm K−1. Interestingly, antenna substrates fabricated from this material exhibited stable dielectric performance even when subjected to various extreme environmental tests, such as high-temperature aging (350 °C), 85 °C/85% RH aging, and thermal shock cycling with a temperature differential of 596 °C. Therefore, this exceptional stability makes it an ideal candidate material for high-reliability, lightweight antenna substrates in extreme environments.","PeriodicalId":84,"journal":{"name":"Journal of Materials Chemistry C","volume":" 24","pages":" 10623-10633"},"PeriodicalIF":5.1,"publicationDate":"2026-04-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148314682","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
