AI Technical Summary
Technical Problem
Existing boron-containing compounds have insufficient luminescent properties when used as luminescent materials.
Method used
Using compounds represented by formulas (I) and (II) as luminescent materials, boron-containing compounds BBCz-R are prepared through a synthetic reaction and used in organic photoluminescent elements and organic electroluminescent elements to form luminescent layers or be doped into other luminescent materials.
Benefits of technology
A luminescent material with excellent luminescence efficiency and delayed fluorescence characteristics has been achieved, which improves the spectral purity and chromaticity coordinates of the luminescent element and exhibits high external quantum efficiency and narrow emission spectrum.
