- Abstract
Superoxide anion (O2.−), a short‐lived, highly active reactive oxygen species, participates in many physiological processes. This work reports the design of a chemiluminescent probe (CLO) based on 1,2‐dioxetane‐phenol with a selective and sensitive response to O2.−. The CLO consisted of a 1,2‐dioxetane‐phenol as a chemiluminophore core bearing a trifluoromethanesulfonate (Tf) moiety and methyl acrylate group. Upon reacting with O2.−, the Tf was specifically cleaved from the CLO, resulting in chemiluminescence generation. The CLO emits chemiluminescence at 450–650 nm (λmax=540 nm), representing visible and red chemiluminescent molecules, responsive to O2.−. The CLO processes high sensitivity (Limit of detection=66 nM) and selectivity for O2.− with and has been applied to track O2.− fluctuations in living cells and animals. In addition, CLO successfully detected and visualized O2.−‐related biochemical processes, making it promising as an important imaging tool for studying redox in biology and medicine.
