An insight into the communication between β-olefin/phenyl olefin-mediated acceptors and porphyrin π-system: a way to establish porphyrin based chemodosimeters and chemosensors

Abstract

Porphyrins bearing electron acceptors attached to β-carbon through olefin or phenyl–olefin bridges act as chemodosimeters for CN⁻ as well as chemosensors for F⁻, CN⁻ and OAc⁻ ions depends on acceptor strength and position.
