  Difluoroboron β-diketonate (BF2bdk) dyes display reversible mechanochromic luminescence (ML) in the solid state. A series of BF2bdk dyes with methyl, phenyl, naphthyl and anthracyl groups (i.e. arene substituents and bdk ligands: Me–Ph = mbm, Ph–Ph = dbm, Np–Ph = nbm, An–Ph = abm) were prepared to test the effects of π conjugation length and arene size on ML properties. Solid-state emission spectra were recorded for powders, spin-cast films, and dye coated weighing paper. The materials emit at various wavelengths from blue to red, depending on the conjugation length. Additionally, emission spectra were recorded for smeared solids and their recovery was tracked at room temperature over time. All dyes except for BF2mbm show emission changes upon mechanical perturbation, with increasing π conjugation correlating with more dramatic, redshifted fluorescence, however, their recovery is significantly affected by the aromatic substituents. The thermal and structural properties of the dyes in the solid state were also investigated by differential scanning calorimetry (DSC) and atomic force microscopy (AFM).

  二氟硼δ²-二酮酸酯（BF2bdk）染料在固态下显示出可逆的机械变色发光（ML）。一系列带有甲基、苯基、萘基和蒽基（即炔取代基和 Bdk 配体）的 BF2bdk 染料：制备了 MeâPh = mbm、PhâPh = dbm、NpâPh = nbm、AnâPh = abm），以测试Ï共轭长度和炔烃尺寸对 ML 特性的影响。记录了粉末、旋铸薄膜和染料涂层称重纸的固态发射光谱。根据共轭长度的不同，这些材料的发射波长从蓝色到红色不等。此外，还记录了涂抹固体的发射光谱，并在室温下跟踪其随时间的恢复情况。除 BF2mbm 外，其他所有染料在受到机械扰动时都会发生发射变化，Ï 共轭度的增加与更剧烈的红移荧光相关，但它们的恢复受到芳香取代基的显著影响。此外，还通过差示扫描量热法（DSC）和原子力显微镜（AFM）研究了固态染料的热和结构特性。

  The invention provides luminescent solid-state compositions comprising difluoroboron beta-diketonates wherein the compositions can exhibit mechanochromic luminescence. The mechanochromic effect on the luminescence can be reversible, such as thermally reversible. Various solid-state forms of the invention can have emission spectra that differ from the properties of the respective difluoroboron beta-diketonate in solution. The mechanochromic effect can be stimulated by pressure such as hand-writing, and can be reversed over a period of minutes to hours at room temperature. The invention also provides methods of making and methods of using the solid-state compositions, such as for sensors and for information displays for use in biological sensing, and in art, design, and consumer products. Compositions of the invention, such as compositions in nanoparticulate form, or contained within a matrix material, can be used in conjunction with fluorescence microscopy to provide information concerning pressures and tensions within and external to living cells, tissues, or organisms.
