Fluorescent Chemosensor for Detection and Quantitation of Carbon Dioxide Gas

摘要

CO₂ sensing is of great societal implications, as CO₂ is a component of gas mixtures from many natural and anthropogenic processes with huge impacts on globe climate and human well-being. Herein we report a CO₂ assay scheme over a wide concentration range, utilizing a fluorogen with an aggregation-induced emission feature and a liquid with tunable polarity and viscosity. The CO₂ sensing process is specific, quantitative, and interferent tolerant.
