溶液法在有机发光二极管(OLED)的制备工艺中具有成本低和材料利用率高的优势.在溶液加工有机发光二极管(SOLED)的多层架构中,空穴传输层所用材料(HTM)对于级联空穴注入至关重要.然而,常用的商业HTM材料TFB由于能级不匹配和上层溶剂再溶解问题而使器件性能受限,因此需要可交联的HTM (X-HTM)以获得更好的器件性能.在本研究中,我们设计合成了两种新型小分子X-HTMs,FTPA-V和FPCz-V,这两种材料中均引入了热交联的乙烯基团和吸电性三氟甲基基团.所合成的X-HTMs具有优异的膜形貌和溶剂抗性,优化了界面接触.使用X-HTMs显著提高了蓝绿红光SOLEDs的效率和寿命.特别是采用FPCz-V的蓝光SOLED显示出超过150小时的寿命(LT95),是蓝光SOLED寿命的新记录.X-HTMs的电化学稳定性、高键解能和高三线态能级能有效地减少激子湮灭并延长寿命.这些发现体现了交联HTM材料的潜力,推动了稳定的溶液加工发光技术的发展.

Intranasal administration of stem cell-derived exosomes for central nervous system diseases

引用

Neural Regeneration Research 2024年第6期19卷 1249-1255页

作者： Shuho Gotoh Masahito Kawabori Miki Fujimura Department of Neurosurgery Hokkaido University Graduate School of Medicine

Exosomes, lipid bilayer-enclosed small cellular vesicles, are actively secreted by various cells and play crucial roles in intercellular communication. These nanosized vesicles transport internalized proteins, mRNA, miRNA, and other bioactive molecules. Recent findings have provided compelling evidence that exosomes derived from stem cells hold great promise as a therapeutic modality for central nervous system disorders. These exosomes exhibit multifaceted properties including antiapoptotic, anti-inflammatory, neurogenic, and vasculogenic effects. Furthermore, exosomes offer several advantages over stem cell therapy, such as high preservation capacity, low immunogenicity, the ability to traverse the blood-brain barrier, and the potential for drug encapsulation. Consequently, researchers have turned their attention to exosomes as a novel therapeutic avenue. Nonetheless, akin to the limitations of stem cell treatment, the limited accumulation of exosomes in the injured brain poses a challenge to their clinical application. To overcome this hurdle, intranasal administration has emerged as a non-invasive and efficacious route for delivering drugs to the central nervous system. By exploiting the olfactory and trigeminal nerve axons, this approach enables the direct transport of therapeutics to the brain while bypassing the blood-brain barrier. Notably, exosomes, owing to their small size, can readily access the nerve pathways using this method. As a result, intranasal administration has gained increasing recognition as an optimal therapeutic strategy for exosomebased treatments. In this comprehensive review, we aim to provide an overview of both basic and clinical research studies investigating the intranasal administration of exosomes for the treatment of central nervous system diseases. Furthermore, we elucidate the underlying therapeutic mechanisms and offer insights into the prospect of this approach.
