Understanding changes to excited state properties under the influence of an external stimuli, such as pressure or temperature, is important in the context of optimizing molecular components for a number of applications including sensors and imaging reagents. Herein, we use UV/vis, fluorescence and excitation spectroscopies, and fluorescence lifetime measurements supported by calculations to probe the effect of hydrostatic pressure on the excited state characteristics of a conformationally‐divergent mechanochromic compound in toluene and methylcyclohexane. We demonstrate that hydrostatic pressure can be used to manipulate the equilibria between excited state conformers. This work provides new perspectives for mechanoresponsive materials and as attractive alternative to conventional ratiometric sensors.
