Fluoride-ion-binding promoted photoinduced charge separation in a self-assembled C60 alkyl cation bound bis-crown ether-oxoporphyrinogen supramolecule

Author affiliations

Abstract

A bis-crown ether-oxoporphyrinogen was newly synthesized and self-assembled concurrently with C60 alkyl ammonium cations at the crown ether sites and F anions (through hydrogen bonding) at the oxoporphyrinogen core. Ultrafast photoinduced charge transfer processes within the donor–acceptor conjugate were promoted by fluoride ion binding and this was established using various spectroscopic methods and transient absorption studies.
