Synthesis of bodipy-based organic dye as a fluorescent sensor for detection of metal ions

Abstract

In this study, a novel BODIPY-based organic dye was designed to be used in a heavy-metal ion complexation studies. It was derivatized by Schiff base at meso-position of the BODIPY. In the first proposed synthesis route, pyrrole and 4-carboxybenzaldehyde condensed to give dipyrromethane. The product cannot be used in the next step because it was decomposed. The modified version of synthesis route was proposed. BODIPY dye was synthesized from pyrrole and 4-carboxybenzaldehyde. The product was contaminated by impurities which cannot be completely eliminated. Therefore, the target molecule was not obtained and the consequential experiments were not conducted.
