Paragraph 0078; 0079; 0080, (2017/08/28)
The invention provides a pure organic room-temperature phosphorescent material with a structure as shown in formula (I) or formula (II), and also provides a preparation method for the pure organic room-temperature phosphorescent material with the structure as shown in formula (I) or formula (II). The invention discloses a series of pure organic room-temperature phosphorescent materials based on a naphthalimide derivative. The pure organic room-temperature phosphorescent materials are characterized in that pure organic electron-donating groups are introduced into molecules, so that the molecules are excited by an outside light source to generate a charge transfer state (ICT) in the molecules, and ICT can promote intersystem crossing, so that generation of room-temperature phosphorescence is facilitated. The pure organic phosphorescent material provided by the invention has the advantages of being simple and convenient to synthesize, low in cost, easy to chemically modify, low in toxicity, environmentally friendly and the like.
