AI Technical Summary
In the existing technology, the host material of delayed fluorescence material combinations cannot achieve sufficient luminescence performance, especially in terms of driving voltage and luminescence lifetime, where there is room for improvement.
A combination of a host material with a specific structure and a delayed fluorescence material is used, specifically including compounds with specific structures, compounds represented by general formulas (1), (2) and (3), and a delayed fluorescence material to form a composition for use as the luminescent layer of an organic light-emitting element.
This has resulted in an organic light-emitting element that features low voltage drive, long lifespan, and high luminous efficiency, thereby improving light-emitting performance.
