Novel chromene-derived fluorescent probe for detection of cyanides by imine-controlled ESIPT
TL;DR: In this paper, a chromogenic and fluorogenic chromene-derived fluorescent probe 5 with a unique imine-controlled excited-state intramolecular proton transfer (ESIPT) mechanism was first developed to sense cyanides with excellent selectivity and high sensitivity in aqueous environments.

Addition of α-Cyanomethylpyridine to Naphthalimide via Trifluoromethyl-Directed CH Functionalization: Cyanide Sensing in Aqueous Media.
TL;DR: A colorimetric anion sensor based on the activated C-H group is described, and the selective and reusable detection of cyanide using the sensor is demonstrated, providing a new way to develop activated CH-based anion receptors.
