Peptide-based folding systems have intriguing features with a variety of advanced applications. Rational and precise control over their dynamic behaviors exploring the role in recognition guests are conducive to construct adaptive molecular machines host–guest chemistry. In this work, peptide arms were conjugated on benzothiophene skeleton rotatable axis terminated pyrene as luminescent signaling domains. The show adaptiveness toward solvation that impacts expression chirality chiroptical properties by which circularly polarized luminescence can be initiated. Beyond signaling, domains function chiral clamps include aromatic imides charge-transfer interaction high selectivity. size planes, steric effects, electron deficiency determined binding affinity. Supramolecular clamping would disassociate aggregation into complexes invert chirality. study advances design flexible applications chemistry sensing.

Circularly Polarized Luminescence in Rotaxanes and Catenanes

ChemistryEurope, Journal Year: 2025, Volume and Issue: unknown

Abstract Rotaxanes and catenanes have proven to be key structures in the development of artificial molecular machines with a variety applications. Among them, study modulation optical properties, mainly light emission, been widely explored. The growing interest chiral mechanically interlocked molecules has enabled this research extended chiroptical particular circularly polarized luminescence. In review, we discuss progress on topic, from seminal examples number reported very recent years. Both rotaxanes fixed or static CPL response are reviewed, but also designs that exploit switching mechanisms by these architectures modulate switch their both solution and/or aggregate solid state.
