Abstract

Organic light-emitting diodes (OLEDs) were successfully fabricated by the solution-process based on spin-coating technique for preparation of organic thin films of newly developed organic materials. The performances of OLED devices could be improved by insertion of the newly developed hole-transporting materials based on triphenylamine end-capped with carbazole dendrons while blue, green, and red OLEDs with excellent emission efficiency were obtained from newly developed blue emitters based on fluorine-triphenylamine end-caped with pyrene and fluorine-anthracene bearing either triphenylamine or pyrene moieties, newly developed green emitters based on benzothiadiazole-thiophene end-capped with carbazole-triphenyl-amine, respectively, with optimization of both device structures with a simple structure and emitting material concentration. The solution-proceed and these newly developed materials could be alternative for development of low cost full-color-flat-panel OLED displays.
