3′‐O‐(2‐Nitrobenzenesulfonyl)fluorescein as a Fluorescent Probe for Hydrogen Polysulfides by Straightforward One‐Step Deprotection

Abstract

AbstractInvited for this month's cover is the group of Prof. Hatsuo Maeda at Hyogo Medical University, Japan. The cover picture features selective visualization of hydrogen polysulfides (H2Sn, n ≥ 2) over other related species through a fluorogenic reaction of 3′‐O‐(2‐nitrobenzenesulfonyl)fluorescein, that was screened as the best practical H2Sn probe among 2‐ or 4‐nitrobenzenesulfonylated fluorescein derivatives. More information can be found in the Research Article by K. Tsukamoto, H. Maeda, and co‐workers.
