Thermally activated delayed fluorescent (TADF) materials can fully harvest both singlet and triplet excitons for light emission, becoming a research hot topic in the field of organic electroluminescence. However, the majority of fluorescent materials often suffers from aggregation-caused quenching, which is unfavorable for their application and development. As a new type of TADF material, aggregation-induced delayed fluorescence (AIDF) material exhibits aggregation-induced fluorescence enhancement, which has drawn great interest of researchers. The molecular design of AIDF materials, its photophysical properties and device research are of great significance. In this review, the recent progress of the donor-acceptor type AIDF materials based on different electron acceptors is summarized. The light-emitting mechanism, design strategy as well as the latest developments of the of AIDF materials and organic light-emitting diodes are elaborated, and their prospects in the future are also forecasted.

Key words: aggregation-induced emission, thermally activated delayed fluorescence, D-A type molecule, organic light- emitting diode
