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 and exhibit emission wavelength maxima (λem,max) at 448 and 710 nm, respectively. Upon grinding, the λem,max of ground and ground are bathochromically shifted to 900 nm, i.e., Δλem,max () = 452 nm or 1.39 eV. Polymorphs and thus represent the first examples of mechanochromic luminescent materials with λem,max in the IR region.

机械激发后最大900 nm处的最大发射光致变色9蒽金(I)异氰化物配合物

在机械刺激下,异硫氰酸9-蒽金(I)配合物3显示出其发射颜色从可见区到红外区(IR)的红移,这在其大小上是空前的。在受到机械刺激之前,多晶型物分别在448和710 nm处显示出发射波长最大值(λem,max)。在研磨时,λ EM,最大地面地面被红移至900nm,即,Δλ EM,最大值)= 452纳米或1.39电子伏特。多晶型物因此代表了在红外区域具有λem,max的机械变色发光材料的第一个例子。
