Abstract

A non-PET and non-PCT fluoroionophore has been designed and synthesized based on the combination of a biaryl boron-dipyrromethene fluorophore with an oligoethyleneglycol bridge. A specific red-shift response of absorption for NaClO₄ in acetonitrile was demonstrated based on conformational restriction triggered by cation recognition at the bridge. The concentration of Na⁺ can be determined accurately using fluorescence due to a high extinction coefficient (ε = 50000), a high fluorescence quantum yield (Φ_f = 0.68), and the sharpness of absorption and emission peaks of the boron-dipyrromethene derivative.
