Near‐infrared (NIR) thermally activated delayed fluorescence (TADF) materials have great potential for applications in many fields. However, it is more challenging for such kinds of materials to achieve efficient NIR emission in comparison to visible light. Herein, as a proof of concept, three acceptors are regularly aligned to optimize intramolecular charge transfer (ICT) interactions in donor‐π‐acceptor molecules to improve bathochromic shift and TADF performance, which successfully supports the application in NIR OLEDs.
