Upon mechanical stimulation, 9-anthryl gold(I) isocyanide complex 3 exhibited a bathochromic shift of its emission color from the visible to the infrared (IR) region, which is unprecedented in its magnitude. Prior to exposure to the mechanical stimulus, the polymorphs 3α and 3β exhibit emission wavelength maxima (λ) at 448 and 710 nm, respectively. Upon grinding, the λ of 3α and 3β are bathochromically shifted to 900 nm, i.e., Δλ (3α) = 452 nm or 1.39 eV. Polymorphs 3α and 3β thus represent the first examples of mechanochromic luminescent materials with λ in the IR region.
在机械刺激下，9-蒽基金（I）异氰化物配合物 3 的发射颜色从可见区红移到了红外（IR）区，这在其程度上是前所未有的。在暴露于机械刺激之前，多晶型体 3α 和 3β 的发射波长最大值（λ）分别为 448nm 和 710nm。研磨后，3α 和 3β 的 λ 发生红移至 900nm，即 Δλ（3α）=452nm 或 1.39eV。多晶型体 3α 和 3β 因此代表了具有 λ 在 IR 区的首例机械变色发光材料。
