Luminescent Chromism of Boron Diketonate Crystals: Distinct Responses to Different Stresses

An organic crystal adopts a molecular packing that can be readily perturbed by external stresses like tensile forces, isotropic pressure, and anisotropic pressure through mechanical smashing, grinding, and compressing, respectively. As a result, the crystals display mechanoluminescence (ML) in response to different mechanical stimuli. The present study provides a model in which three distinct MLs are combined into one organic material.
