Cyano and Isocyano-substituted Tetraphenylethylene with AIE Behavior and Mechanoresponsive Behavior
文献摘要：
Dual-functional materials with AIE behavior and mech-anoresponsive behavior have attracted considerable attention due to their promising applications in mechano-sensors,optical storage,solid-state optoelectric devices and bioimage systems.AIEgens bearing tetraphenylethylene(TPE)core become elementary building blocks in many fluorescent functional materials.In this article,cyano-and isocyano-electronic withdrawing groups are incorporated with TPE skeleton to form tetracyanophenylethylene(TPE-CN)and tetraisocyanophenylethylene(TPE-NC).Their structures are con-firmed by NMR,Mass Spectra and single crystal X-ray measure-ment.These two isomers reflect aggregation-induced emission(AIE)property in solution state and mechanochromic behavior in solid state.Interestingly,their luminescent intensities,quantum yields and fluorescent lifetime in solid state have an obvious increase upon grinding.The theoretical calculation of these two compounds clarify their difference in optical properties.The mechanochromic mechanism is also intensively explained by powder X-ray measurements.
