Item Open Access Intramolecular energy transfer through linear polyenes : effect of spacers(1990) Blessing, Gerd; Holl, Norbert; Port, Helmut; Wolf, Hans Christoph; Effenberger, Franz; Kesmarszky, Thomas; Schlosser, HubertThe optical properties of linear polyenes terminally substituted with different molecules (mainly anthryl- and TPP-substituents) have been studied. Bicyclic spacers within the polyene chain affect the quantum yields but do not interrupt intramolecular energy transfer between the endgroups.Item Open Access Energy transfer through conjugated polyenes(1989) Maier, Stefan; Port, Helmut; Wolf, Hans Christoph; Effenberger, Franz; Schlosser, HubertFrom an analysis of absorption, fluorescence and excitation spectra of linear polyene molecules with 4 to 13 double bonds and one or two aromatic substituents at the chain ends we conclude that the aromatic substituents can be excited individually, and that intramolecular energy transfer from one end group via the polyene to the other end group is possible.Item Open Access Synthesis and optical properties of terminally substituted conjugated polyenes(1988) Effenberger, Franz; Schlosser, Hubert; Bäuerle, Peter; Maier, Stefan; Port, Helmut; Wolf, Hans ChristophLong-chain, conjugated polyenes can function as molecular wires. This is shown by the photophysical properties of polyenes containing naphthyl, anthryl, and tetraphenylporphyrinyl (TPP) terminal groups. When the anthryl group in 1, which is obtainable by a sequence of Wittig reactions, is selectively excited, strong TPP emission is observed.
