Description

technical field [0001] The invention relates to the technical field of organic luminescent materials, in particular to a multifunctional aggregation-induced luminescent enhancement compound and its preparation method and application. Background technique [0002] Among all kinds of organic light-emitting materials, anthracene-based light-emitting materials have become an important category of organic electroluminescent materials due to their high fluorescence quantum efficiency, easy substitution and modification, and a wide range of substituents. However, the rigid structure and planarity of anthracene make it prone to aggregation fluorescence quenching problems. At the same time, anthracene-based small-molecule light-emitting materials have poor film-forming properties and are prone to recrystallization in organic light-emitting diodes (OLEDs). [0003] At present, the research on anthracene-based luminescent materials focuses on different derivatives of anthracene. CN1036...
