Abstract

The invention provides an improved coupling light-emitting material, and aims to obtain the coupling light-emitting material with high thermal stability and high refractive index. The structural general formula is disclosed in the invention, wherein n = 1, 2; m=0, 1, 2. A series of substituted aniline CPL based on thiazolo [2, 3, 4-kl] phenothiazine is synthesized. According to the molecules, benzene rings in triphenylamine are connected through carbon-sulfur bonds to form silane naphthalene [3, 2, 1-de] anthracene, so that substituted arylamine materials are synthesized. The rigidity and planarity of the material are enhanced, so that the CPL thermal stability is improved, the refractive index of the material is obviously improved, and coupling light emission is facilitated. The inventionalso provides a preparation method of the coupling light-emitting material.

Description

technical field [0001] The invention relates to the field of optoelectronic technology, in particular to a light-coupling material and a preparation method thereof. Background technique [0002] Organic light-emitting diodes (organic lighting-emitting diodes, OLEDs), due to active light emission, large viewing angle, fast response speed, wide temperature range, low driving voltage, low power consumption, high brightness, simple production process, light and thin, and can The advantages of flexible display have shown great application prospects in the fields of OLED display and lighting, attracting the attention of researchers and companies. [0003] Whether it is a bottom-emitting device or a top-emitting device, most of the electro-generated light is lost inside the device, and the generated light cannot be effectively taken out of the device. At present, the general solution is to coat an organic light coupling layer (CPL) on the outside of the device electrode to increas...
