摘      要：Dual-functional materials with AIE behavior and mechanoresponsive behavior have attracted considerable attention due to their promising applications in mechano-sensors,optical storage,solid-state optoelectric devices and bioimage *** bearing tetraphenylethylene(TPE)core become elementary building blocks in many fluorescent functional *** this article,cyanoand isocyano-electronic withdrawing groups are incorporated with TPE skeleton to form tetracyanophenylethylene(TPE-CN)and tetraisocyanophenylethylene(TPE-NC).Their structures are confirmed by NMR,Mass Spectra and single crystal X-ray *** two isomers reflect aggregation-induced emission(AIE)property in solution state and mechanochromic behavior in solid ***,their luminescent intensities,quantum yields and fluorescent lifetime in solid state have an obvious increase upon *** theoretical calculation of these two compounds clarify their difference in optical *** mechanochromic mechanism is also intensively explained by powder X-ray measurements.
