Abstract

AbstractA series of planar‐stereogenicity ferrocenes, important as chiral promoters in enantioselective catalysis, is characterized in terms of relationships between structure and electronic properties. The enantiomers of six selected model cases are then successfully discriminated in voltammetry experiments on electrodes modified with electrodeposited inherently chiral oligomer films, in terms of significant potential differences, specular inverting probe or selector configuration. Small substituent changes do not alter the enantiomer peak sequence, but result in significant modulation of peak potential differences, which appear consistent with the availability of chiral/selector matching elements. The present stereogenic plane case, combined with former ones involving stereogenic centers, axes, and/or helices, shows that the inherent chirality strategy in electroanalysis can be effective with all four rigid stereogenic elements.
