Abstract: A novel high molecular compound is provided. The high molecular compound includes a repeating unit. The repeating unit has a fluorenediyl group, a hole-transport skeleton, and an electron-transport skeleton. The hole-transport skeleton is bonded to the fluorenediyl group through a substituted or unsubstituted first arylene group. The electron-transport skeleton is bonded to the fluorenediyl group through a substituted or unsubstituted second arylene group. In an excited state, intramolecular charge transfer occurs between the hole-transport skeleton and the electron-transport skeleton.
