Abstract

Dendritic luminescent materials are a kind of three-dimensional(3D) organic optoelectrical functional materials composed of the central core and the dendrons. They are regarded as an important category of organic luminescent materials for the development of cost-effective and high-efficiency organic light emitting devices(OLEDs) because they possess well-defined molecular structure like small molecules and excellent solubility like polymers. Thermally activated delayed fluorescence(TADF) dendrimers-based OLEDs can realize 100% internal quantum efficiency by utilizing triplet excitons through enhanced reverse intersystem crossing process from the lowest triplet state to singlet state. Thus

TADF dendrimers represent a promising approach towards highly efficient dendritic luminescent materials. During these years

significant progress has been made on the molecular design and device performance of TADF dendrimers. In this review

we classify the TADF dendrimers according to their core structure and summarize their research progress with the emphasis on molecular structure

photophysical properties and device performances. Finally

the perspectives and the key challenges on developing TADF dendrimers are discussed.
