Despite recent great advances in the area of mechanochromic luminescence (MCL), the control over the direction for the mechanical-stimuli-induced shift of the emission maximum still remains a challenging task. Herein, triphenylimidazolylbenzothiadiazoles as a new class of solid-state emissive fluorophores are developed. The switching between bathochromically and hypsochromically shifted MCL has been achieved for the crystals of a bromo-substituted derivative simply by changing the crystallization solvent.
