Fluorescent Organic Nanoparticles of Biginelli-Based Molecules: Recognition of Hg²⁺ and Cl^– in an Aqueous Medium

Abstract

Biginelli-based molecules (1-3) have been synthesized and developed as a new class of fluorescent organic nanoparticle-based chemosensors. Chemosensor 2 has shown excellent selectivity and sensitivity for detection of Hg(2+) in an aqueous medium. It can detect Hg(2+) up to 1 nM, and the resultant 2Hg(2+) complex can detect Cl(-) ions (micromolar level) in an aqueous medium.
