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.
