- A concise colorimetric and fluorimetric probe for sarin related threats designed via the covalent-assembly approach
-
A turn-on signal from zero background allows sensitive detection of a weak signal and is highly desired. The covalent-assembly probe design principle is powerful in this regard. Herein, we report an embodiment of this principle (NA570) for detection of Sa

- Synthesis of Sterically Protected Xanthene Dyes with Bulky Groups at C-3′ and C-7′
-
Substitution of the xanthene scaffold with bulky groups at C-3′ and C-7′ is expected to protect the electrophilic central methine carbon against nucleophilic attack and inhibit stacking. However, such structures are not readily prepared via traditional xa
