The invention discloses an organic luminescent material with mesotropic ultra-long room temperature phosphorescence emission characteristics, a synthesis method and application thereof. The structure of this organic luminescent material is shown in formula (1): In formula (1), R 1 is halogen, and R 2 is aryl or heteroaryl. At the same time, the synthesis method and application of the organic luminescent material are also disclosed. The organic material containing halogenated phthalimide and trifluoromethyl structure of the present invention has simple synthesis process and easy purification, and the obtained solid material can emit ultra-long room temperature phosphorescence under the action of external force, that is, it has strong With the characteristics of afterglow luminescence, good thermal stability, high luminous efficiency, and adjustable luminous color, it is very suitable for display lighting, pressure sensing, security and anti-counterfeiting, biological imaging and other fields. |
