Pentaporphyrin with flexible, chiral nucleosidic linkers: unexpected duality of the physico-chemical properties of its core

Abstract

A new star-like pentaporphyrin, bearing nucleosidic linkers, has been synthesized, and the unexpected duality of the physico-chemical properties of its core is reported; beside the quenching of the fluorescence of the peripheral porphyrins by the central chromophore, this pentaporphyrin exhibits an unexpected shielding of the redox capabilities of its central core.
