ABSTRACT
A simple donor-acceptor (D-A) molecule, 9-(1H-benzotriazol-1-ylmethyl)-9H-carbazole (CzBtrz), shows superhigh heat-resisting phosphorescence property with an ambient lifetime of 988.54 ms at 545 nm. The phosphorescence performance can maintain the stability in a large temperature region from 77 to 350 K (ΔT = 273 °C), exceeding those of other room-temperature phosphorescence (RTP) systems, and it exhibits white light via thermally activated delayed fluore- scence and phosphorescence dual emission.
