reported mechanochromic luminescent materials contain a single luminophore with two fl uorescent states, and thus their fl uorescence can be switched between two colors or two different intensities. [ 5a , 6 ] However, examples exhibiting mechanochromic phosphorescence are rather rarely seen in literature, except for a few metal complexes showing mechanochromic phosphorescence with short lifetimes.
