摘　　要：Two o-carborane based tetraphenylethene(TPE)cationic cyclophanes O1.4PF_(6)and O2.4PF_(6)were syn thesized through an S_(N)2 reaction.Their structures were confirmed both possessing Z-shaped cavities in single crystal analysis.The optical properties of these macrocycles were systematically investigated using UV–vis spectroscopy and fluorescence techniques.It is worth noting that the introduction of a methoxy group to the TPE unit enables the synthesis of a near-infrared-emitting macrocycle O2.4PF_(6).The recogni tion behaviors of these two macrocycles towards nucleotides were investigated using various technique including fluorescence titration,UV–vis titration,and transmission electron microscopy(TEM).Interest ingly,these cyclophanes exhibited aggregation-induced emission(AIE)effects in water or under the in duction of nucleotides.
