Spirally configured cis-stilbene/fluorene hybrid materials for organic light-emitting diode
The present invention provides a series of spirally configured cis-stilbene/fluorene hybrid materials, which are spirally-configured cis-stilbene/fluorene derivatives having glass transition temperatures ranged from 105 C. to 130 C., decomposition temperatures ranged from 385 C. to 415 C., reversible electron transport property, and balanced charges motilities. Moreover, a variety of experimental data have proved that the yellow fluorescent, the green phosphorescent, the yellow phosphorescent, and the red phosphorescent OLEDs using this spirally configured cis-stilbene/fluorene derivatives as the electron transport layers having hole blocking functions can indeed show excellent EQE, current efficiency, power efficiency, maximum luminance, and device lifetime performances much better than the conventional or commercial yellow fluorescent, green phosphorescent, yellow phosphorescent, and red phosphorescent OLEDs.
