Abstract
AbstractHerein, a simple aza‐aromatic compound dibenzo[a,c]phenazine (DPPZ), which exhibits single‐molecule white light with a ternary emission, consisting of simultaneous fluorescence (S1→S0) and dual room‐temperature phosphorescence (RTP, T2→S0 and T1→S0) is reported. The Commission Internationale de l' Éclairage coordinates of DPPZ powder are (0.28, 0.33). To everyone's knowledge, this is the first case to achieve single‐molecule white emission with ternary emission of fluorescence and dual RTP. This finding provides a prototype strategy to realize low‐cost, stable pure organic single‐molecule white light emission with three standard primary colors through further precise modulation of excited states.
