Abstract

CD and UV-vis measurements were carried out to demonstrate chirality induction-promoted by chiral covalently linked groups and non-covalently bound Δ- and Λ-[Ru(phen)(3)](2+) enantiomers-in metallo-porphyrin-calixarene and metallo-porphyrin-bis-calixarene non-covalent assemblies, respectively.
