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.
