An amphiphilic A2+-S-D triadmolecule and its reference compounds, S−D, A2+-S, and S type molecules, were synthesized and studied using time-resolved transient absorption spectroscopy. The three moieties in the triad, i.e., an electron acceptor moiety (A2+, viologen), a sensitizer moiety (S, perylene), and an electron donor moiety (D, ferrocene), were linearly combined by sigma-bonded tunneling bridges
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.
