Abstract
A fluorescence based oxygen sensor can be prepared comprising a polyaniline polymer doped with one or more pyrene carboxylic acids. The polyaniline has the formula: and the pyrene carboxylic acids have the formula:Pyrene-R—COOH  (II);wherein R is an aliphatic linking group having 1 to 11 carbon atoms, n represents half the degree of polymerization, x is about 0.5, and (1−x) is about 0.5. The sensor can be coated onto a support. Upon excitation with an appropriate wavelength, the polyaniline/pyrene coating fluoresces. Upon exposure to oxygen the fluorescence rapidly decays.
