Dual-ligand chiral MOFs exhibiting circularly polarized room temperature phosphorescence for anti-counterfeiting

作者： Hongrui Zheng Qingqing wang Xinchao wang Fei wang Shangda Li jian Zhang State Key Laboratory of Structural Chemistry Fujian Institute of Research on the Structure of Matter Chinese Academy of Sciences Fujian Key Laboratory of Polymer Materials College of Chemistry and Materials Science Fujian Normal University

Advanced chiral optical materials exhibiting circularly polarized room-temperature phosphorescence（CPRTP） possess significant research value. This study facilitates the synthesis of chiral metal-organic frameworks（CMOFs） with good CPRTP performance by implementing a dual-ligand strategy. By self-assembling the luminescent ligand H2BIIM with the chiral ligands L-or D-H2IDPA in the presence of Zn（II） ions, two robust three-dimensional（3D） CMOFs were successfully constructed. These complexes demonstrated intense fluorescence and exhibited prolonged yellow room-temperature phosphorescence（RTP） with a duration of up to 6 s. Notably, they exhibited both circularly polarized fluorescence(glum= ±7.57 × 10-3) and CPRTP(glum=±2.68 × 10-3). These unique properties were effectively utilized in the creation of multi-color anti-counterfeiting patterns,underscoring their promising potential for a wide range of applications.

Spinal cord injuries lead to significant loss of motor, sensory, and autonomic functions, presenting major challenges in neural regeneration. Achieving effective therapeutic concentrations at injury sites has been a slow process, partly due to the difficulty of delivering drugs effectively. Nanoparticles, with their targeted delivery capabilities, biocompatibility, and enhanced bioavailability over conventional drugs, are garnering attention for spinal cord injury treatment. This review explores the current mechanisms and shortcomings of existing treatments, highlighting the benefits and progress of nanoparticle-based approaches. We detail nanoparticle delivery methods for spinal cord injury, including local and intravenous injections, oral delivery, and biomaterial-assisted implantation, alongside strategies such as drug loading and surface modification. The discussion extends to how nanoparticles aid in reducing oxidative stress, dampening inflammation, fostering neural regeneration, and promoting angiogenesis. We summarize the use of various types of nanoparticles for treating spinal cord injuries, including metallic, polymeric, protein-based, inorganic non-metallic, and lipid nanoparticles. We also discuss the challenges faced, such as biosafety, effectiveness in humans, precise dosage control, standardization of production and characterization, immune responses, and targeted delivery in vivo. Additionally, we explore future directions, such as improving biosafety, standardizing manufacturing and characterization processes, and advancing human trials. Nanoparticles have shown considerable progress in targeted delivery and enhancing treatment efficacy for spinal cord injuries, presenting significant potential for clinical use and drug development.

Cotton fibers elongate rapidly after initiation of elongation, eventually leading to the deposit of a large amount ofcellulose. To reveal features of cotton fiber cells at the fast elongation and the secondary cell wall synthesis stages, wecompared the respective transcriptomes and metabolite profiles. Comparative analysis of transcriptomes by cDNA arrayidentified 633 genes that were differentially regulated during fiber development. Principal component analysis (PCA)using expressed genes as variables divided fiber samples into four groups, which are diagnostic of developmental *** grouping results are also found if we use non-polar or polar metabolites as variables for PCA of developingfibers. Auxin signaling, wall-loosening and lipid metabolism are highly active during fiber elongation, whereas cellulosebiosynthesis is predominant and many other metabolic pathways are downregulated at the secondary cell wall synthesisstage. Transcript and metabolite profiles and enzyme activities are consistent in demonstrating a specialization process ofcotton fiber development toward cellulose synthesis. These data demonstrate that cotton fiber cell at a certain stage has itsown unique feature, and developmental stages of cotton fiber cells can be distinguished by their transcript and metaboliteprofiles. During the secondary cell wall synthesis stage, metabolic pathways are streamed into cellulose synthesis.
