The huge market demand for organic light‐emitting diodes (OLEDs) has attracted a significant number of researchers to explore robust and cheap luminescent materials for application in high‐performance and low‐cost OLEDs. This concept article presents a new class of organic luminescent materials which demonstrate aggregation‐induced delayed fluorescence (AIDF). This material type can perform particularly well when applied in nondoped OLEDs, with devices exhibiting excellent electroluminescence (EL) efficiencies and very small efficiency roll‐off. Recent works on typical AIDF materials, investigating molecular design strategies, photophysical properties and EL performance in nondoped OLEDs, are discussed. These newly emerged organic luminescent materials are promising candidates for highly efficient nondoped OLEDs and have potential practical applications.
