Abstract

An anthracene carboxyimide derivative was synthesized as a colorimetric and fluorogenic sensor to determine NO₂^- with a rapid response (<4 min), excellent selectivity and a low detection limit (84 nM). Paper strips containing the sensor were applied to visually determine the NO₂^- content in food.
