A functionalized dialkylperylene and a modified terrylenetetracarboxdiimide (TTCDI) were joined together by a hexanediyl spacer. The resulting bichromophoric molecule 4 is a suitable model system for donor-acceptor energy transfer studies at the single-molecule level. With its absorption and fluorescence maximum at shorter wavelengths (lambda(max) = 450 nm, lambda(n) = 458 nm) the dialkylperylene acts as the donor, while the TTCDI with lambda(max) = 665 nm and lambda(fl) = 705 nm is the acceptor molecule. The synthetic route to the new bichromophoric molecule and its optical properties (UV/V is, fluorescence spectroscopy) are presented herein. Energy transfer from the perlyene to the terrylene moiety was confirmed by conventional ensemble fluorescence excitation and emission spectroscopy. Single bichromophores 4 embedded in polyvinylbutyral were imaged with a scanning confocal optical microscope at room temperature by selectively exciting the perylene chromophore and detecting the terrylene emission.
Photooxygenation of Alkynylperylenes. Formation of Dibenzo[<i>jk</i>,<i>mn</i>]phenanthrene-4,5-diones
[GRAPHICS]3-(1-Alkynyl)perylenes undergo oxygenation when subjected to irradiation with visible light under aerated conditions. The structures of novel oxygenated products formed in this manner are assigned as regioisomeric dibenzo[jk,mn]phenanthrene-4,5-diones.
