The first fluorescent chemical traps for (1)O(2) have been developed. DPAXs react specifically with (1)O(2) to yield the corresponding endoperoxides, DPAX-EPs (see scheme; X = H, Cl, F). DPAXs scarcely fluoresce, while DPAX-EPs are strongly fluorescent. Since the fluorescence of these probes is unaffected by H(2)O(2), superoxide, and nitric oxide, they are useful for the selective detection of (1)O(2) in biological systems.

A tetrafluoro-substitutedfluoresceinderivative covalently linked to a 9,10-diphenyl anthracene moiety has been synthesized, and its photophysical properties have been characterized. This compound, denoted Aarhus Sensor Green (ASG), has distinct advantages for use as a fluorescent probe for singlet molecular oxygen, O2(a1Δg). In the least, ASG overcomes several limitations inherent to the use of the

Derivatives of 9,10-diphenylanthracene-2,3-dicarboxylic acid were synthesized by the Diels-Alder reaction of 1,3-diphenylisobenzofuran with adducts of furan (or silvan) and the corresponding maleic (fumaric) acid derivative or with trans-cyclohex-4-ene-1,2-dicarbonitrile, followed by aromatization.
