Photochemistry and photophysics of 1,4-dewarnaphthalene

Richard V. C. Carr; Bongsub Kim; Jeffrey K. McVey; N. C. Yang; Wolfgang Gerhartz; Josef Michl

Abstract Photoexcited 1,4-dewarnaphthalene (1) rearranges in high efficiency to excited naphthalene in both the singlet and the triplet manifold. Assuming the relative efficiencies of fluorescence to intersystem crossing of 1 are similar to those of substituted benzenes, the rearrangement of triplet 1 to triplet naphthalene may be adiabatic. The relative efficiencies of fluorescence to rearrangement to singlet excited naphthalene from singlet excited 1 at 77 K depends on the wavelength of exciting light, the shorter the wavelength, the more efficient the rearrangement.
