Abstract

See full text

The present application provides an electroluminescent material, a method for manufacturing an electroluminescent material, and a light emitting device, by employing the strong electron-withdrawing group such as cyano, pyridine, pyrimidine, or s-triazine to enhance the electron-withdrawing property of the fluorenone receptor unit, a captodative electron effect between the electron donor unit and the electron acceptor unit in the molecule is enhanced, so that the intermolecular charge transfer property is enhanced while the red light shifts, thereby further reducing the energy level difference between the single-line energy level and the triplet energy level of the target molecule, to realize a long life span, red light emitted electroluminescent material, a method for manufacturing the electroluminescent material and a light emitting device.
