โœฆ Synopsis

Five different verdins, including one zinc metal chelate, were examined by laser flash techniques. Triplet molar absorption coefficients, triplet and singlet oxygen quantum yields and triplet lifetimes were determined. Zinc methyl pyroverdin (ZNMPV), copro II verdin trimethyl ester (CVTME) and deuteroverdin methyl ester (DVME) have the highest triplet and singlet oxygen quantum yields. ZNMPV and CVTME have the longest triplet lifetimes. Our data are consistent with singlet oxygen as the primary modality for phototherapy and it is suggested that DVME and CVTME may be useful agents.

Photoexcited 1,4dewarnaphthalene (1) rearranges in high efficiency to excited naphtbdene in both the singlet and the . triplet manifold. Assuming the relative efficiencies of fluorescence to intersystem crossing of 1 are similv to those of substituted benzenes, the rearrangement of triplet 1 to trip
