Organic light emitting diode (OLED) devices are one of the most promising alternatives to liquid crystal displays (LCDs) for flat panel display (FPD) applications. The OLED technique is based on organic semiconductors used either as hole- or electron transporting materials or as an emitter. Working on common problems of performance and life time in OLED preparation, improved charge transport molecules and polymers such as triarylamine- and poly(para-phenylene)-have been developed. Some useful materials include: (1) cyclic triarylamine-derivatives possessing enhanced glass transition temperatures; (2) triarylamine based low molecular mass hole-transport molecules and hole-transport polymers with pendant oxetane groups for processing out of solution and subsequent cross-linking; and (3) fluorenyl-segmented poly(para-phenylene)s with defined electrochemical properties. Provided is a polymer precursor that is useful as a hole transport polymer in OLED and other organic electronic devices.
有机发光二极管(OLED)设备是平板显示(FPD)应用中最有前途的液晶显示器(LCD)替代品之一。OLED技术基于有机半导体,可以用作空穴或电子传输材料或发射体。在解决OLED制备过程中的性能和寿命等常见问题时,已经开发出了改进的电荷传输分子和聚合物,例如三芳胺和聚(对苯)-。一些有用的材料包括:(1)具有增强玻璃化转变温度的环状三芳胺衍生物;(2)基于三芳胺的低分子量空穴传输分子和空穴传输聚合物,具有侧链氧杂环基团,可用于溶液处理和随后的交联;(3)具有定义的电化学性质的芴段化聚(对苯)-。提供的是一种聚合物前体,在OLED和其他有机电子器件中作为空穴传输聚合物非常有用。
