The activity of synthetic pores, ion channels, transporters and carriers is usually determined with fluorescent probes in vesicles or by conductance measurements in planar lipid bilayers. Elaborating on more colorful alternatives, we here introduce 5(6)-carboxynaphthofluorescein (CNF) as an intravesicular pH
