Abstract
A simple ESIPT-based fluorescence probe (HMBT-LW) was developed for the detection of superoxide (O2˙−).
Highlights
A simple Excited-state intramolecular proton transfer (ESIPT)-based fluorescence probe (HMBT-LW) was developed for the detection of superoxide (O2À)
have developed a thiocarbamate functionalised methoxyhydroxybenzothiazole (HMBT)-LW was synthesised over two steps and was shown to rapidly detect low concentrations of O2À, fully reacting within two minutes
Reactive oxygen species (ROS) are the transient by-products generated from the electron transport chain.[1]
Summary
ESIPT-based fluorescence probe for the ratiometric detection of superoxide† A simple ESIPT-based fluorescence probe (HMBT-LW) was developed for the detection of superoxide (O2À). HMBT-LW was synthesised over two steps and was shown to rapidly detect low concentrations of O2À (limit of detection = 7.4 lM), fully reacting within two minutes.
