Abstract
- We synthesized 2-amino-1,3-propanediol-modified boron dipyrromethene (BODIPY) in a rapid two-step synthesis, with a total reaction time of 6 hours. The resulting fluorophore's emission was significantly quenched by polar solvents but increased fourfold upon the addition of Hg<superscript>2+</superscript> ions. Notably, this BODIPY fluorophore exhibited high selectivity toward Hg<superscript>2+</superscript> ions over various other metal ions (Li<superscript>+</superscript>, Na<superscript>+</superscript>, K<superscript>+</superscript>, Ca<superscript>2+</superscript> Co<superscript>2+</superscript>, Cu<superscript>2+</superscript>, Ni<superscript>2+</superscript>, Pb<superscript>2+</superscript>, Zn<superscript>2+</superscript>, Mn<superscript>3+</superscript>, Ag<superscript>+</superscript>, and Fe<superscript>3+</superscript>), with a binding constant of 7.36 × 10<superscript>4</superscript> M<superscript>−1</superscript>. The binding mechanism was investigated using proton nuclear magnetic resonance (<superscript>1</superscript>H NMR) and infrared (IR) spectroscopy and revealed that 2-amino-1,3-propanediol moieties chelated the Hg<superscript>2+</superscript> ions. These chelated Hg<superscript>2+</superscript> ions could be displaced by hexadentate EDTA molecules. Furthermore, treating BODIPY with an acid restored fluorescence emission, while a base diminished it, and this process was reversible. This rapidly synthesized BODIPY fluorophore holds great potential for Hg<superscript>2+</superscript> ion detection. [ABSTRACT FROM AUTHOR]
