Helicity Induction in Hydrogen‐Bonding‐Driven Zinc Porphyrin Foldamers by Chiral C₆₀‐Incorporating Histidines

Abstract

High chiral amplification is exhibited by a new series of zinc porphyrin appended, hydrogen-bonded foldamers on binding with C60-incorporating chiral histidines as a result of the cooperation of two discrete noncovalent interactions: zinc porphyrin/imidazole coordination and zinc porphyrin/C60 π–π stacking (see picture).
