Abstract
The present invention provides a series of spirally configured cis-stilbene/fluorene hybrid compounds and an optoelectronic device comprising the same. The compound comprises a seven-membered ring portion. The seven-membered ring portion is composed of a cis-stilbene fragment, and a tetrahedral coordination bridging atom fragment, wherein the cis-stilbene fragment has at least one substituent, the substituent is independently a substituted or unsubstituted triazine group, pyrimidine group or phenyl group. The compounds have glass transition temperatures ranged from 156° C. to 202° C., decomposition temperatures ranged from 419° C. to 509° C., reversible electron transport property, and balanced charges motilities. In addition, a variety of experimental data have proved that these spirally configured cis-stilbene/fluorene hybrid materials can indeed be used as a hole-blocking type electron-transporter for phosphorescent OLEDs.
