Ultrasound‐Induced Mechanoluminescence and Optical Thermometry Toward Stimulus‐Responsive Materials with Simultaneous Trigger Response and Read‐Out Functions

“…Light emission by mechanical stimulation-termed mechanoluminescence (ML) -has been reported for a broad range of materials, from inorganic crystals and polycrystalline ceramics [1] to organic and hybrid compounds. [2] Correlations between the level of applied stress and the intensity of luminescence enable a variety of applications, [3,4] for example, in stress sensors, crack detectors, or smart displays. [5][6][7][8][9][10] ML induced by ultrasonic excitation (USML) was evaluated for the ability to visualize ultrasonic power distribution, [11,12] but also for security and anticounterfeiting purposes, [13] or as a photon source in photocatalysis, [14] photobioreactors, [15] and optogenetics.…”

Two Calcium Coordination Polymers with Multi‐Stimuli‐Responsive Properties

“…In addition, the facts that the density of 2 is higher than that of 1 , and the structure of 1 contains more solvent molecules than that of 2 also prove this point. According to the literatures, [23–27] the change of effective conjugation degree in the structure caused by grinding is an important reason for whether the materials show blue‐shifted or red‐shifted luminescence response to the stimulus. Upon grinding, the lattice of 1 is destroyed.…”

“…This may be due to the destruction of the strong face‐to‐face π⋅⋅⋅π interactions in the structure caused by grinding, and then the reduction of the aggregation of ligands, leading to the reduction of the effective conjugation degree in the structure. Although the phenomenon of red‐shift or blue‐shift of the emission of SRL materials caused by grinding stimulus has been reported, [23–30] skeleton isomers exhibit different responses to grinding stimuli are still very rare.…”

“…Interestingly, the initial structure and luminescence properties can be recovered under fumigation, or immersion treatment, thereby realizing a reversible response. So far, the vast majority of LCP type SRL materials show the response that the emission wavelength moves from high energy level to low one under mechanical force stimulation, [23–28] that is, the emission peak is red‐shifted, while the blue‐shifted response of the emission wavelength from low energy level to high one is relatively rare [29–30] . The adjustment of the luminescence color before and after grinding stimulation in a controllable way is of great significance for the application of MCL materials.…”
