Vapor‐Phase Detection of Perfluoroalkyl Acids using Amplifying Fluorescent Polymers
Abstract
ABSTRACT Perfluoroalkyl acids are a subclass of persistent toxic per‐ and polyfluoroalkyl substances (PFAS) whose volatility enables airborne exposure pathways that remain largely unmonitored. Therefore, suitable technologies are urgently needed for real‐time monitoring of PFAS acids in the vapor phase. Herein, we report a new platform for selective vapor‐phase detection of volatile perfluoroalkyl acids using amplifying fluorescent polymers. The designs incorporate highly fluorinated moieties to create a fluorous microenvironment that enhances selectivity and pyridine‐based selectors that react with volatile PFAS acids through proton‐transfer reactions. Ratiometric fluorescence detection was employed in sensing experiments, and polymer thin films exhibited rapid responses (
