Abstract

A turn-off luminescent probe RuHPIP for Cu²⁺ detection in aqueous solution has been developed through reversible and selective complexation. Cu²⁺ can specifically bind with the ligand of 2-hydroxyphenyl imidazo in the RuHPIP structure and induce luminescence quenching of the sensor instantaneously under a physiological environment. The probe enabled rapid and reversible detection of Cu²⁺ with detection limit of 7.23 × 10^-8 M, and it can image Cu²⁺ in live pea aphids.
