The first example of tuning the energetics thermally activated delayed fluorescence (TADF) molecules to access anti-Kasha dual-emission and room-temperature phosphorescence materials through a strategy for structural modification is developed here. To rapidly construct library structurally diverse carbonyl-bridged triarylamine-based TADF materials, copper-mediated cyclization heterocycles 2-bromobenzoic acids was further time. Novel exhibit distinct white light emission with CIE coordinates (0.32, 0.32) in solid film can be fabricated into low-cost robust organic LEDs. Ultralong room temperature (URTP) displayed cyan afterglow up seven seconds lifetime 508.8 ms could used encryption.
