Two water soluble 1O2 traps: dipotassium 1,3-diphenylisobenzofuran-5,6-dicarboxylate and tetrapotassium 9,10-diphenylanthracene-2,3,6,7-tetracarboxylate have been prepared in good yields and a new access to the anthracene skeleton is described.The key-step of this synthesis consists of a cycloaddition between 1,3-diphenylisobenzofurans and dimethyl 7-oxabicyclo-5-heptene-2,3-dicarboxylate; the adducts thus obtained undergo dehydration to afford the corresponding anthracenes.

The first fluorescent chemical traps for 1O2 have been developed. DPAXs react specifically with 1O2 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 H2O2, superoxide, and nitric oxide, they are useful for the selective detection of 1O2 in biological systems.
