Abstract

original image

Anion-triggered chiral switch: Reversible switching between fac and mer isomers in tris(2,2′-bipyridine)iron(II) complexes, the ligands of which are substituted at the 5-position with various peptides of different lengths and sequences, has been achieved (see figure). The remote stereocontrol at the FeII center by a domino-type chiral information transfer along an achiral peptide main-chain was observed even over 3 nm (50 bond lengths).
