This invention relates to compositions and methods useful for measuring pH generally, and intracellular pH specifically, and, more particularly, to a new class of fluorescent and fluorinated (NMR sensitive) aromatic compounds having excitation emission wavelengths in the ultraviolet or or visible portions of the electromagnetic spectrum, useful as pH indicators, as well as fluorine containing analogs useful in NMR spectroscopic determinations.
