Abstract

A novel fluorescence probe (L) was prepared and its sensing behavior toward metal ions was investigated. Probe L exhibited colorimetric response toward Hg²⁺ and fluorescence enhancement with an obvious blue shift toward Cu²⁺ in CH₃CN/H₂O (v/v, 9:1). The association constant for probe L-Hg²⁺ and probe L-Cu²⁺ in CH₃CN/H₂O (v/v, 9:1) was determined as 1.5 × 10⁴ M⁻¹ and 5.3 × 10⁸ M⁻², respectively. The detection limit of probe L for the analysis of Hg²⁺ and Cu²⁺ was determined as 22.69 ppb and 155.53 ppb, respectively.
