| Popis: | A detailed study of the electronic behavior of a series of even nonalternant polycyclic aromatic hydrocarbons derived from fluoranthene is presented. Compounds were synthesized that contained substantial barriers to rotation of substituents into conjugation with the parent hydrocarbon. The heavy atom bromine was incorporated into several compounds to probe its ability to quench fluorescence by spin-orbital coupling. External heavy atom solvent effects on the quenching of fluorescence were also investigated. Fluorescence spectra are presented that clearly indicate that intramolecular heavy atom effects (HAEs) can be transmitted through phenyl substituents conjugated with a polycyclic aromatic hydrocarbon |
