摘要：
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 pi-pi 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.
