of live cells. However, in situ metabolic imaging studies are hampered by the lack of fluorescent chemical structures that allow direct monitoring of small metabolites under physiological conditions with high spatial and temporal resolution. Herein, we describe SCOTfluors as novel small-sized multi-colored fluorophores for real-time tracking of essential metabolites in live cells and in vivo and for

We introduce 7-fluoro-4-N,N-dimethylaminosulfonyl-2,1,3-benzothiadiazole and 7-fluoro-4-N,N-dimethylaminosulfonyl-2,1,3-benzoselenadiazole as new fluorogenic reagents for amines. These reagents are nonfluorescent themselves and can easily react with nonfluorescent amines to produce environment-sensitive fluorophores. Herein, we report the synthesis of the new reagents and the fluorescence properties of the reagents and their amine derivatives as well as the reactivity of the new reagents toward amines.
