Studies on the preparation and properties of two new, selective fluorescent probes CD18, 1 and C18, 2 for potassium are described.The probes incorporate the 1,10-diaza-18-crown-6 chelating group for the ion and the coumarin group as the fluorophore.The probes are compared with the known reagent PBFI.C18 shows considerably greater selectivity for potassium over sodium than PBFI.
