摘　　要：A new series of Ir(Ⅲ)carbene complexes with luminescent mechanochromism derived from trans-cis isomerization has been developed.Through the introduction of π-conjugating groups into the acyclic carbene ligand,the mechanochromic trans-and cisconfigurations can be readily interconverted,leading to dual emissive properties in the solid state.Moreover,the solid-or film-forming solvent system can control the dual emission and mechanoresponsive properties in the solid state.The potential uses of a single emissive complex to develop multicolor emissive and multiple stimuli-responsive films have been studied.
