Anion-enhanced excited state charge separation in a spiro-locked N-heterocycle-fused push-pull zinc porphyrin
This article presents a new type of push–pull charge transfer complex, viz., a spiro-locked N-heterocycle-fused zinc porphyrin, ZnP-SQ, that is shown to undergo excited state charge separation, which is enhanced by axial F⁻ binding to the Zn center. Spectroelectrochemical studies are used to identify the spectra of charge separated states and charge separation upon photoexcitation of ZnP is established.
