A general purpose reporter for cations: absorption, fluorescence and electrochemical sensing of zinc(ii)
Abstract
A fluorescent sensor has been synthesized that comprises a pyrene moiety tethered to a [2,2′:6′,2″]-terpyridyl β1
≈ 5.1 and log
β2
≈ 9.9 were derived for the 1 ∶ 1 and 1 ∶ 2 complexes, respectively, in
