Abstract
Luminescent materials – developed using appropriate molecular engineering – are capable of signaling about various irritants with high sensitivity. In particular, mechanofluorochrome materials show fluorescence emission that is sensitive to mechanical stimulation (pressure, shear, cracking, grinding). Mechanically sensitive compounds are attracting increasing interest and various molecules are synthesized that respond to mechanical stress by changing their fluorescent characteristics (emission wavelength, intensity, polarization, Stokes shift). For a deeper understanding of the relationship between the structure of the dye and its mechanofluorochrome properties, a review of compounds possessing this property is given in the work.
