Lanthanide ions as sensitive probes in intermolecular energy transfer and organic photochemistry. Annual progress report
Research progress is reported in the following areas: (1) the spectroscopic properties and behavior of positively charged organic sensitizers, for lanthanide ion energy acceptors, (2) distant interaction between nonconjugated electronic systems in rigid model molecules, (3) generation of stable paramagnetic species from selected organic heterocyclic energy donors, (4) preliminary experiments of hydroxycarbonium ion-europium energy transfer, and (5) photochemical reactions of donors of excitation energy competing effectively with transfer of energy to lanthanide acceptors. Titles of preprints and manuscripts attached to the report are: Electronic Absorption and Emission of Aromatic Hydroxycarbonium Ions,'' On the Configuration of Dienestrol,'' Through-Space Interaction Between Nonconjugated Napthalene and Phenanthrene in a Rigid Molecule,'' and Formation of LongLived Free Radicals from Acylpyridinium Salts with Alkali.''
