A Naphthalimide‐Based Fluorescence “Turn‐On” Probe for the Detection of Pb²⁺ in Aqueous Solution and Living Cells

Abstract

An easily available naphthalimide-based fluorescent probe NPA for Pb(2+) detection was successfully developed. NPA exhibited an obvious fluorescence turn-on response toward Pb(2+) in aqueous solution and in living cells. Moreover, a series of model compounds were rationally designed and synthesized in order to explore the sensing mechanism and binding mode of NPA with Pb(2+) .
