• A phenothiazine derivative of FCO‐CzS with changeable mechanoluminescence is reported, which, upon continuous mechanical stimulus, shows mechanoluminescent emission from blue to white and yellow. Careful analysis of the experimental results, coupled with the well‐understood photoluminescence theory, show that the molecular conformation transition of the phenothiazine group from quasi‐axial to quasi‐equatorial is responsible for this dynamic mechanoluminescence effect. Conformation‐dependent emission: The phenothiazine derivative FCO‐CzS with changeable mechanoluminescence shows mechanoluminescent emission from blue to white and yellow upon continuous mechanical stimulus. The unique and unusual character of the compound enabled a detailed analysis and deep understanding of its mechanoluminescence.
