摘要

In this study, a naphthalene-1-sulfonamide/2-hydroxybenzaldehyde conjugation as a selective probe (probe L) was designed for the selective recognition of Pb²⁺. Probe L displayed an obvious fluorescence enhancement upon binding to Pb²⁺ in CH₃CN solution. The association constant of probe L-Pb²⁺ complex was calculated to be 7.68 × 10⁸ M⁻¹, and the detection limit for Pb²⁺ was found to be 23.2 ppb.
