The mechanochromic and thermochromic luminescence properties of a molecular copper(I) iodide cluster formulated [Cu(4)I(4)(PPh(2)(CH(2)CH=CH(2)))(4)] are reported. Upon mechanical grinding in a mortar, its solid-state emission properties are drastically modified as well as its thermochromic behavior. This reversible phenomenon has been attributed to distortions in the crystal packing leading to modifications of the intermolecular interactions and thus of the [Cu(4)I(4)] cluster core geometry. Notably, modification of the Cu-Cu interactions seems to be involved in this phenomenon directly affecting the emissive properties of the cluster.
报道了一种分子碘化亚铜簇合物[Cu(4)I(4)(PPh(2)(CH(2)CH=CH(2)))(4)]的力致变色和热致变色发光性能。在研钵中机械研磨时，其固态发光性质以及热致变色行为发生了剧烈的变化。这种可逆现象归因于晶体堆积的扭曲，导致分子间相互作用的改变，从而改变[Cu(4)I(4)]簇核的几何形状。值得注意的是，Cu-Cu 相互作用的改变似乎直接参与了这一现象，从而直接影响了簇合物的发光性质。
