A linear fluorescence-quenching response in an amidine-functionalised solid-state sensor for gas-phase and aqueous CO2 detection

Abstract

An amidine-functionalised metal–organic framework (MOF) was shown to be an effective chemosensor in the presence of gaseous and aqueous phase CO₂ by virtue of a quenched fluorescence response. This work demonstrates how multifunctional MOFs with high selectivity for CO₂ may be exploited to develop CO₂ chemosensors.
