Abstract

The invention belongs to the technical field of organic light emitting materials, and discloses an aggregation-induced light emitting material simultaneously containing a triphenylethylene structure and a tetraphenylethylene structure. During synthesis, a triphenylethylene intermediate containing a functional group and a tetraphenylethylene intermediate containing a functional group are connected together by coupling reaction. A synthesis method of the invention has the advantages of simple process and convenient purification; and the synthesized organic light emitting material simultaneously containing the triphenylethylene structure and the tetraphenylethylene structure has the advantages of obvious aggregation-induced light emitting performance, high thermal stability, high glass-transition temperature and high luminous intensity and is suitable for preparing a light emitting layer material in an organic electroluminescent material device.

Description

technical field

[0001] The invention belongs to the technical field of organic luminescent materials, in particular to an aggregation-induced luminescent material containing both triphenylethylene and tetraphenylethylene structures, a synthesis method and application thereof. Background technique

[0002] Due to their huge potential applications in flexible display and lighting, organic light-emitting devices such as organic light-emitting diodes (OLEDs) have been highly valued by the scientific and industrial circles in recent years, and are one of the current research and development hotspots.

[0003] Organic light-emitting materials play a pivotal role in the technology of organic light-emitting devices, which directly affect the luminous efficiency and service life of light-emitting devices. Most organic light-emitting materials have high fluorescence quantum yields in the dilute solution state, but become weakly fluorescent or do not emit light at all in the solid stat...
