Acridinium Benzoates for Ratiometric Fluorescence Imaging

Abstract Acridinium benzoate was developed as a unique ICT‐based fluorescent scaffold for both ratiometric and turn‐on fluorescence imaging through decaging of the phenolic hydroxyl groups. Two fluorescent probes, Acr1‐H 2 O 2 and Acr1‐ β ‐gal , were developed for the fluorescence imaging of H 2 O 2 and β‐galactosidase in vivo.
