On–off‐switchable, persistent, room‐temperature phosphorescence (373 ms) is realized in organic solids based on bis(4‐(9 H ‐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.
