ORGANIC ELECTROLUMINESCENT MATERIAL AND USE THEREOF

Resumen de: US2025361246A1

The present disclosure relates to an organic electroluminescent material having a structural formula as shown in formula (A) or (B). Based on a conventional B-N resonance structure, in such material, an aromatic ring that does not participate in the resonance is fixed to a resonance ring by means of a dimethyl-substituted methylene group to form a larger rigid structure, thereby decreasing non-radiative vibration, reducing delayed fluorescence lifetime and reducing efficiency roll-off. Moreover, the introduction of the dimethyl-substituted methylene distorts the B-N planar skeleton, which can reduce fluorescence quenching at high concentrations, thereby obtaining relatively high efficiency. In addition, when Cy1 and Cy2 are different, especially after a heteroatom is introduced, this type of asymmetric structure can further distort the molecular plane, reduce film aggregation and quenching, and achieve a higher current efficiency.
