The invention belongs to the field of organic luminescent materials, and specifically discloses a carborane derivative, the structural formula of which is as follows: R 1 and R 2 are derivatives of H or phenanthrene, and R 1 and R 2 are not H at the same time. The carborane derivatives described in the present invention can precisely control the luminescent wavelength of the compound through charge transfer emission and (or) localized state emission, and obtain a series of white light molecules; by introducing carborane groups, the luminescence caused by the aggregation of solid molecules can be avoided Quenching, high absolute quantum yield of luminescence, good thermal stability and easy sublimation, etc., have practical application value. |
