title: Fluorescence sensing of caffeine in aqueous solution with carbazole-based probe and imaging application in live cells.
abstract: The host-guest interaction of caffeine in aqueous solutions has been achieved by using carbazole based imino-phenol receptors with oxopurines influences their fluorescence properties and can be exploited for 'turn-ON' fluorescence sensing of caffeine. This new fluorescent probe with high sensitivity and selectivity for detection and first time imaging of caffeine in living cells was developed in aqueous media.
