Title:
FUSED RING COMPOUND, PREPARATION METHOD FOR SAME, AND USES THEREOF
Document Type and Number:
WIPO Patent Application WO/2020/000826
Kind Code:
A1
Abstract:
Disclosed is a fused ring compound having the structure as represented by formula (I) or formula (II). In the fused compound, by controlling an effective conjugate of an aromatic ring and a heterocycle, while increasing the hole performance of the compound, balanced electron transport performance is favored. The compound is provided with a high triplet state and glass state transformation temperature, the material molecules of the compound are not prone to crystallization, and the compound serving as the main material of a light-emitting layer ensures highly efficient transfer of energy to an object material. An adjustment of a substituent group of the fused ring compound further increases electron and hole transport performances, reduces the difference between a singlet state and a triplet state, expands a compositing area for a carrier, and prevents triplet exciton annihilation. Also disclosed is an organic electroluminescent component having at least one function layer containing the fused ring compound. The fused ring compound serves as the main material of the light-emitting layer, matches with an adjacent carrier transport layer in terms of energy level, and, while increasing the luminous efficiency of the component, reduces a driving voltage for the component.
