Abstract We demonstrate the room temperature tribophosphorescence from a simple anthracene boronic ester, 9‐(pinacolboryl)anthracene ( 1 ). Both 1 and 9,10‐bis(pinacolboryl)anthracene ( 2 ) show fluorescence and delayed emission at room temperature in the solid‐state. Under mechanical stress, 1 displays tribophosphorescence. In contrast, 2 shows mechanofluorochromism under similar conditions. Detailed optical, computational, and crystal structural studies are carried out to rationalize the tribo
