Such surface-functionalization utilizes the principles of charge-transfer (CT) interaction. The incorporation of [6]helicene molecules with unique electronic and optical properties and subsequent arrangement of AuNPs caused chirality induction to intrinsically non-chiral plasmon-active nanostructures. The created nanostructures enabled the excitation of chiral plasmon and its application in highly sensitive enantioselective detection of small chiral molecules by surface-enhanced Raman spectroscopy (SERS). The chiral plasmonic response of such a system was shown to be fully controlled via the helicity of the parent [6]helicene. Upon calibration, it allowed us to directly determine the enantiomeric composition of non-racemic mixtures of (R)/(S)− 1-phenylethanol and (R)/(S)− 2-butanol.
