Abstract

Hetero- and homochiral diastereomeric bis(metallahelicene)s have been synthesized. They possess a rare Pt^III-Pt^III scaffold bridged by benzoato ligands. It is shown that heterochiral (P,M)-bis(Pt ^III-[6]helicene) can isomerize into the homochiral (P,P)- and (M,M)-bis(Pt^III-[6]helicene). A theoretical study shows a unique σ-π conjugation between the two π-helices and the σ-Pt ^III-Pt^III scaffold that impacts the strong chiroptical properties.
