Co‐Assembly of Tetraphenylethylene‐Derived Glutamic Acid and Arginine via Chiral Recognition for Boosting Circularly Polarized Luminescence

Chiral recognition is an important topic in supramolecular chemistry. Here, we present a chiral recognition‐driven supramolecular strategy that simultaneously controls nanoscale morphology and amplifies circularly polarized luminescence (CPL). A novel pair of enantiomeric glutamic acid derivatives functionalized with aggregation‐induced emission (AIE)‐active Tetraphenylethylene (TPE) was designed as chiral probes. While these compounds self‐assemble into CPL‐active irregular aggregates, their co‐assembly with arginine enantiomers exhibits remarkable chirality‐dependent behaviors. The homo‐chiral ( L ‐Arg/TPE‐ L ‐Glu) assemblies showed as a nanotube structured and dramatically enhanced CPL activity (|g lum | = 0.114), representing an 8‐fold increase over hetero‐chiral combinations (|g lum | = 0.014). The system enables simultaneous chiral discrimination through both CPL signal amplification and morphological differentiation. This work establishes a way in supramolecular chirality engineering, demonstrating chiral recognition can lead to the nanoscale architectures as well as enhanced chiroptical properties.
