چکیده
• Soft crystals exhibiting mechanochromic luminescence (MCL). Reviewing the systematic studies on MCL behaviors of soft crystals. Controlling molecular conformation and packing structure Emphasizing remarkable steric effects substituents properties MCL. are a class smart materials that can switch their photophysical or mechanical in response to gentle external stimuli. A representative stimuli-responsive behavior is (MCL), i.e., reversible color change solid-state photoluminescence induced by Together with rapid growth area including fluorescence, room-temperature phosphorescence (RTP), thermally activated delayed fluorescence (TADF), white-light emission (WLE), circularly polarized (CPL), number exhibit have been reported during past decade. In typical crystals, switches bathochromic direction upon amorphization grinding recovers original recrystallization heating exposure organic solvents. Relatively few known hypsochromically shifted MCL, two-step self-recovering mechanical-stimuli-induced single-crystal-to-single-crystal (SCSC) transitions. Rational design guidelines control mechanoresponsive not yet established. This review summarizes substituent effect Recent provide useful insights into electronic differences crystal structure, properties, behaviors.

Materials with mechnoresponses are a new discipline in organic soft matter synthesis. One mechanoresponse, thixotropy, is the tendency of a material to become less viscous upon the addition of mechanical stress such as shaking. Separately in other gels, a visible color change during the gel-to-solution transition has been observed. While gels with either thixotropic or color-change qualities ha...
