摘要

Two blue-emitting oligomers, namely FDPA1 and FDPA2 containing 9,10-diphenylanthracene core end-capped with triphenylamine-substituted fluorene has been synthesized and characterized. The Spiro-configuration end-capping groups imparts two compounds with pronounced morphological stability (T-g > 185 degrees C, T-d > 420 degrees C) and excellent hole injection ability (E-HOMO > -5.27 eV) with the advantageous optical characteristics of corresponding core. Scanning electron microscope (SEM) and X-ray diffraction (XRD) reveal that the two oligomers form excellent amorphous films and possess good morphological stability after annealing.
