Abstract
We report a novel, reversible, cell-permeable, pH-sensor, TRapH. TRapH afforded a pH-sensitive ratiometric emission response in the pH range ~3-6, enabling imaging and quantification of pH in living cells. The biological-applicability of TRapH was illustrated via live-tracking of intracellular pH dynamics in living mammalian cells induced by a synthetic H+-transporter.
