Embodiment

[0118] In this embodiment, the first host material H1 and the second host material H2 may be TCTA and B3PYMPM respectively. The structural formula of TCTA is as follows:

[0119]

[0120] The structural formula of B3PYMPM is as follows:

[0121]

[0122] These two host materials can form composite excited states, and can form a type II heterojunction structure.

[0123] The organic fluorescent light-emitting material E1 can be Emitter1, which is a commonly used red fluorescent light-emitting material, and its structural formula is as follows:

[0124]

[0125]And in the present invention, it is more preferred to adopt thermally excited delayed fluorescent material (TADF material), such as Emitter2 (referring to Chem.Commun.Vol48, p11392), and its structural formula is as follows:

Abstract

The invention discloses an organic mixture, a composite containing the organic mixture, an organic electronic device and application. The organic mixture comprises a first main material H1, a second main material H2 and an organic fluorescence radiation material E1, wherein the second main material H2 and the first main material H1 form a composite excited state material. The first main material H1 and the second main material H2 have II-type heterogeneous structures, and the radiation wavelength of the organic fluorescence radiation material E1 is larger than or equal to the radiation wavelength of the composite excited state material formed by the first main material H1 and the second main material H2. According to the solution, a radiation device is low in manufacturing cost, high in efficiency, long in service life and low in roll-off.

Description

technical field [0001] The invention relates to the field of electroluminescent materials, in particular to an organic mixture, a composition containing the same, an organic electronic device, and the application of the organic mixture in the organic electronic device, especially the application in the organic electroluminescent device. Background technique [0002] Organic light-emitting diodes (OLEDs) have great potential for applications in optoelectronic devices such as flat panel displays and lighting due to the synthetic versatility, relatively low fabrication cost, and excellent optical and electrical properties of organic semiconductor materials. [0003] In order to improve the luminous efficiency of organic light-emitting diodes, various light-emitting material systems based on fluorescence and phosphorescence have been developed. Organic light-emitting diodes using fluorescent materials have the characteristics of high reliability, but their internal electrolumines...
