6 H-苯并[4,5]噻吩并[2,3- b ]吲哚是新型高效热激活延迟荧光发射体的新型供体,其EQE超过20%†
摘要:
在此报告中,我们开发了两种新型的基于吲哚的电子供体,即6 H-苯并[4,5]噻吩并[2,3- b ]吲哚(synBTI)和6 H-苯并呋喃[2,3- b ]吲哚(synBFI),用于设计绿色热激活延迟荧光(TADF)发射器。两个TADF发射体2-(6 H-苯并[4,5]噻吩并[2,3 - b ]吲哚-6-基)-5-(4,6-二苯基-1,3,5-三嗪-2-基)苄腈(BTITrz)和2-(6 H-苯并呋喃[2,3 - b ]吲哚-6-基)-5-(4,6-二苯基-1,3,5-三嗪-2-基)苄腈(BFITrz通过合成两个新的供体与一个芳基三嗪受体来合成。详细研究了供体单元中杂原子对TADF发射体的光物理和电致发光性质的影响。光物理分析表明,与同系物BFITrz相比,BTITrz显示出相对较小的单重态-三重态能量分裂,较短的延迟荧光寿命和较高的光致发光量子产率(PLQY)。结果,使用BTITrz发射

A delayed fluorescence material is disclosed. The delayed fluorescence material has a molecular structure that includes an electron donor unit that donates electrons; and an electron acceptor unit that is coupled to the electron donor unit and accepts electrons, wherein the electron acceptor unit includes an indolocarbazole group having at least one acceptor functional-group bound to the indolocarbazole group. Thus, the delayed fluorescence material exhibits high structural and thermal stability as well as high quantum efficiency.
