Abstract

The invention discloses a 9-naphthalene anthracene derivative. The 9-naphthalene anthracene derivative is centered on a bisanthracene group, and utilizes the effect of the naphthalene group on molecular arrangement, so that the molecule presents an anthracene group in a single molecular state. The classic blue light emission of the group, the green light emission of the intermolecular charge transfer state formed when the molecules are stacked, and the yellow light emission of the excimer associations, the three combined effects make this kind of compound a single-molecule white light material. In the present invention, by improving the key chemical structure and preparation process of the 9-naphthalene anthracene derivative, a new single-molecule white light material of the 9-naphthalene anthracene derivative in which an intermolecular charge transfer state is combined with an excimer association is obtained, Moreover, the 9-naphthalene anthracene derivative can be synthesized by a simple synthesis method, and can be used as an electroluminescence material, thereby solving technical problems such as complex preparation of existing single-molecule white light materials, unstable light color, and the like.

Description
