Abstract

A new fluorescent sensor based on the BODIPY fluorophore and the polyamide receptor for Pb²⁺ was designed and synthesized. The sensor is highly selective for Pb²⁺ over relevant competing metal ions, and sensitive to ppb levels of Pb²⁺. It features the most sensitive probe to date for Pb²⁺ ions in water.
