Abstract

On–off-switchable, persistent, room-temperature phosphorescence (373 ms) is realized in organic solids based on bis(4-(9H-carbazol-9-yl)phenyl)methanone. The reversible on–off RTP switching can be controlled by repeatedly chloroform fuming and heating (or grinding). Multi­ple-color fluorescence is also feasible, and they reversibly convert to each other under the stimuli of heating, shearing, and fuming with varied solvents.
