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.
