Title:
TETRADENTATE PLATINUM COMPLEX LUMINESCENT MATERIAL BASED ON TETRAARYLETHYLENE SKELETON STRUCTURE AND USE THEREOF
Document Type and Number:
WIPO Patent Application WO/2023/207622
Kind Code:
A1
Abstract:
The present invention relates to a tetradentate platinum complex luminescent material based on a tetraarylethylene skeleton structure and use thereof. The platinum complex is a compound having a structure represented by chemical formula (I), such material has the property of aggregation-induced emission, the luminescence quantum yield is relatively high, and the excited-state service life is short. Also provided is an organic electroluminescent photoelectric device, comprising a cathode, an anode, and organic layers. The organic layers are one or more of a hole injection layer, a hole transport layer, a luminescent layer, a hole blocking layer, an electron transport layer, and an electron injection layer. At least one of the organic layers contains the compound represented by structural formula (I).
