Description

Technical field: [0001] The invention relates to the field of electroluminescent materials, in particular to a D-A type compound and its application. Background technique: [0002] Organic semiconductor materials have great potential for applications in optoelectronic devices such as light-emitting diodes (OLEDs), such as flat panel displays and lighting, due to their structural diversity, relatively low fabrication cost, and superior optoelectronic performance. [0003] In order to improve the light-emitting performance of organic light-emitting diodes and promote the large-scale industrialization process of organic light-emitting diodes, various organic photoelectric performance material systems with new structures have been widely developed. Among them, donor-acceptor (D-A) optoelectronic materials have been widely used in optoelectronic devices due to their good dual-carrier transport properties and optoelectronic properties. Especially nitrogen-containing donors, such ...
