A cyanide selective off–on fluorescent chemosensor with in vivo imaging in 100% water: solid probe preferred over in situ generation

A nontoxic fluorescent chemosensor [Cu(BP) HMB ] 2 (ClO 4 ) 2 ( 1 ) synthesized in solid phase, exhibits unprecedented selectivity and sensitivity over the allied in situ complexes to perform fluorescence in “turn- off–on ” mode for sensing cyanide in 100% aqueous medium under physiological conditio...

Description
Summary:A nontoxic fluorescent chemosensor [Cu(BP) HMB ] 2 (ClO 4 ) 2 ( 1 ) synthesized in solid phase, exhibits unprecedented selectivity and sensitivity over the allied in situ complexes to perform fluorescence in “turn- off–on ” mode for sensing cyanide in 100% aqueous medium under physiological conditions and for in vivo imaging using the nematode C. elegans . Below μM detection limit, instantaneous and excellent ratiometric responses are also beneficial to detect trace amounts of anthropogenic or biogenic cyanide.
