本文合成了五种新型的金（I）异腈配合物，并对其结构进行了表征。不同末端配体的引入赋予了配合物1 -5不同的性质：i）烷基修饰的配合物1 - 3由于分子间弱的C-H···F相互作用形成的松散堆积而表现出三色或双色力致变色行为，而芳基桥联的配合物4和5由于紧密的π-π堆积而不具有力致变色行为; ii）所有的目标复合物都呈现出突出但不同的聚集诱导发射（AIE）特征，这是由它们结构的固有差异引起的。因此，上述金（I）配合物预期用作荧光检测器和机械传感器。
Five novel gold(I) complexes with various isocyanide ligands have been synthesized and characterized in present work. The introduction of different terminal ligands endows distinct diverse properties to complexes1–5: i) alkyl modified complexes1–3exhibit tricolor or bicolor mechanochromic behaviors due to the loosing packing formed through weak intermolecular C–H···F interactions, while aryl bridged complexes4and5are not mechano-responsive with tight π-π stackings; ii) all the target complexes present prominent but different aggregation-induced emission(AIE) characteristics caused by the inherent difference in their structures. Therefore, the above gold(I) complexes are anticipated to be used as fluorescent detectors and mechanosensors.
