Colorimetric “Naked Eye” Sensing of Anions in Aqueous Solution
Thorfinnur Gunnlaugsson,Paul E. Kruger,Paul R. Jensen,Juliann Tierney,Haslin Dato Paduka Ali,Gillian M. Hussey +5 more
TL;DR: The synthesis and UV-vis and NMR spectroscopic studies of thiourea-based colorimetric sensors for anions are presented, showing that these sensors can recognize anions through hydrogen binding even in competitive pH-buffered aqueous solutions.
Journal ArticleDOI
Design, synthesis and photophysical studies of simple fluorescent anion PET sensors using charge neutral thiourea receptors
Thorfinnur Gunnlaugsson,Anthony P. Davis,Anthony P. Davis,Gillian M. Hussey,Juliann Tierney,Mark Glynn +5 more
TL;DR: Four fluorescent photoinduced electron transfer chemosensors 1-4 for anions showed 'ideal' behaviour where only the fluorescence emission was quenched upon anion recognition, due to enhanced efficiency of electron transfer quenching from the receptor to the excited state of the fluorophore.
Journal ArticleDOI
Fluorescent Photoinduced Electron Transfer (PET) Sensors for Anions; From Design to Potential Application
Thorfinnur Gunnlaugsson,Haslin Dato Paduka Ali,Mark Glynn,Paul E. Kruger,Gillian M. Hussey,Frederick M. Pfeffer,Frederick M. Pfeffer,Cidália M. G. dos Santos,Juliann Tierney +8 more
TL;DR: This mini review highlights the synthesis and photophysical evaluation of anion sensors, for nonaqueous solutions, that have been developed in the laboratories over the last few years, and some of the examples presented can act as dual fluorescent-colorimetric sensors for anions.
