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 complexes 1–5: i) alkyl modified complexes 1–3 exhibit tricolor or bicolor mechanochromic behaviors due to the loosing packing formed through weak intermolecular C–H···F interactions, while aryl bridged complexes 4 and 5 are 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.

已经合成了五种具有各种异氰酸酯配体的新型金（I）配合物，并进行了表征。引入不同的末端配体赋予配合物1-5不同的特性：i）烷基修饰的配合物1-3由于弱分子间C–H···F相互作用而形成的堆积松散，而芳基则表现出三色或双色的机械致变色行为。桥接复合物4和5紧密的π-π堆积对机械无响应; ii）所有目标复合物均表现出突出但不同的聚集诱导发射（AIE）特性，这是由于其结构的固有差异引起的。因此，预期上述金（I）配合物将用作荧光检测器和机械传感器。
