The first examples of single crystals exhibiting salient effects by different structure change mechanisms are reported. The crystals of newly prepared aryl(9-isocyanoanthracene)gold(I) complexes jump in response to two different external stimuli: ultraviolet (UV) irradiation and cooling. The photosalient effect is triggered by photodimerization reaction of the anthracene moieties under photoirradiation. By contrast, the thermosalient effect is caused by anisotropic thermal contraction upon cooling without a chemical structure change. By taking advantage of the multiple-jump feature, we also show sequential jumps of crystals by cooling and then UV irradiation for demonstration of the programmed motion of molecular crystals.
报道了通过不同结构变化机制表现出显著效应的单晶的首个实例。新制备的芳基（9-异氰基蒽）金（I）配合物晶体对两种不同的外部刺激做出响应：紫外线（UV）照射和冷却。光致显著效应是由蒽部分在光照射下的光二聚反应引发的。相比之下，热致显著效应是由冷却时的各向异性热收缩引起的，而无化学结构变化。利用多次跳跃特性，我们还展示了通过冷却然后紫外线照射使晶体连续跳跃，以演示分子晶体的程序运动。
