The role of fluoride in the Tamao oxidation of a model dialkoxysilane has been analyzed by computational means. A potential energy surface was calculated consistent with the typical synthetic methods required for the conversion of alkoxysilanes to alcohols; fluoride generates reactive fluorosilicate

## Abstract Two compounds containing a porphyrin dimer and a perylene tetracarboxylic diimide (PDI) linked by phenyl (**1**) or ethylene groups (**2**) are prepared. The photophysical properties of these two compounds are investigated by steady state electronic absorption and fluorescence spectra a
The fluorescence of pyrenyl residues in complexes with the nucleic acid bases G, C and T, but not A, is strongly quenched by photoinduced electron transfer mechanisms. Site-specifically modified 11-mer oligonucleotide duplexes containing a single modified guanosyl base G\* bearing a covalently attac
