A fluorescent and colorimetric cyanide sensor (4-Br) based on the activated C-H group to conscruct a FRET platform has been described for the first time, along with demonstration of selective and reversible detection of cyanides through it. The sensing mechanism of 4-Br is an integration of ICT and FRET mechanisms, based on the deprotonation of the activated C-H group. Importantly, it is suitable for fluorescence imaging of cyanides in living cell. (C) 2018 Published by Elsevier Ltd.
