以1,3-茚二酮为电子受体的热激活延迟荧光分子的合成及其在有机发光二极管中的应用
Synthesis and Application in Organic Light Emitting Diodes of Thermally Activated Delayed Fluorescence Molecules Based on 1,3-Indione as Acceptor
摘要
Abstract
Novel electron acceptor 2,2-dimethyl-1,3-dione is synthesized and applied for thermally activated delayed fluorescence (TADF) molecular design.We synthesized a series of TADF molecules based on 2,2-dimethyl-1,3-dione with different emission color:IDYD,IDPXZ and ID2PXZ.The organic light emitting diodes (OLEDs) device based on IDYD exhibits blue emission with CIE coordinate of (0.27,0.31),and the maximum external quantum efficiency (EQE) reaches 2.13％.While the OLEDs device based on IDPXZ exhibits orange emission with CIE coordinate of (0.43,0.53) and the maximum external quantum efficiency (EQE) reaches 1.31％.For the OLEDs device based on ID2PXZ exhibits yellow emission with CIE coordinate of (0.41,0.54),and the maximum external quantum efficiency (EQE) reaches 2.55％.The results show that 2,2-dimethyl-1,3-indenone can be used as an electron acceptor for TADF molecule design and have a decent prospect in full-color OLEDs devices.关键词
