文摘
Signaling of water content of biofuel-relevant ethanol and butanol was investigated. Pyranine derivatives showed ratiometric fluorescence signaling toward water content. Sensitivity was greatly improved by derivatization of sulfonate to sulfonamide. Practical application for signaling by easy-to-use smartphone was exploited.
