Blue fluorescent dihydro-indenoindene derivatives with unusual low oxidation potentials as multifunctional OLED materials†
Abstract
Several stable, blue fluorescent bis(diarylamino)dihydro-indenoindene derivatives were synthesized and used as materials for organic light-emitting diodes (OLEDs). The obtained HOMO energies reached up to 4.79 eV and under an applied voltage of 11 V, the current density generated by the hole only devices was 1161 mA cm−2, showing their excellent hole mobility.
