机械荧光致变色或压致变色荧光化学涉及由外源力（诸如研磨、剪切、压缩、张力等）诱导的固态材料的发光性质的切换和调谐。迄今为止，大多数报道的力致变色体系，包括液晶、有机分子、有机金属化合物、聚合物和染料掺杂的聚合物，都显示出可逆的双色变化，其产生于超分子或化学结构的转变。然而，荧光材料，经历机械诱导的荧光变化仍然很少见，这Minireview是集中在这样的材料。主题是根据不同的作用力，需要诱导的相变，包括超分子结构或化学结构的机械控制，和超分子结构和化学结构的机械控制。
Mechanofluorochromic or piezochromic fluorescence chemistry involves the switching and tuning of the luminescent properties of solid-state materials induced by exogenous forces, such as grinding, shearing, compression, tension, and so forth. Up until now, most reported mechanochromic systems, including liquid crystals, organic molecules, organometallic compounds, polymers, and dye-doped polymers, have displayed reversible two-color changes, which arise from either supramolecular or chemical structure transformations. However, fluorescent materials that undergo mechanically induced multicolor changes remain rare; this Minireview is focused on such materials. Topics are categorized according to the different applied forces that are required to induce the multicolor change, including mechanical control of either the supramolecular structures or the chemical structures, and mechanical control of both the supramolecular structures and chemical structures.
