For the development of applications based on mechanochromic luminescent materials, a comprehensive study of the mechanism responsible for the emission changes is required. We report the study of a mechanochromic copper iodide cluster under hydrostatic pressure, which allows control of crystal packing via modification of the intermolecular interactions. In situ single-crystal powder X-ray diffraction analysis and emission measurements under pressure permit one to establish a direct correlation between the molecular structure and luminescence properties and, in particular, to demonstrate that cuprophilic interactions are responsible for the stimuli-responsive luminescence properties of such multinuclear coordination compounds.
对于基于机械变色发光材料的应用开发，需要对导致发射变化的机制进行全面研究。我们报道了在静水压力下对一种机械变色碘化铜簇的研究，该研究通过改变分子间相互作用来控制晶体堆积。压力下的原位单晶粉末X射线衍射分析和发射测量使人们能够建立分子结构与发光性质之间的直接关联，特别是证明亲铜相互作用是此类多核配位化合物的刺激响应发光性质的原因。
