TL;DR: In this article, the potential of a Pt disk working electrode between potentials sufficient to form the radical anionic and cationic species was observed in acetonitrile solutions of Re(L)(CO)3Cl complexes (Bu4NPF6 as electrolyte).
Abstract: Re(L)(CO)3Cl complexes (where L is 1,10-phenanthroline, 2,2‘-bipyridine, or a phenanthroline or bipyridine derivative containing methyl groups) are photoluminescent in fluid solution at room temperature. In acetonitrile solutions, these complexes display one chemically reversible one-electron reduction process and one chemically irreversible oxidation process. λmax for the luminescence is dependent on the nature of L, and a linear relationship between λmax and the difference in electrode potentials for oxidation and reduction is evident. Electrogenerated chemiluminescence (ECL) was observed in acetonitrile solutions of these complexes (Bu4NPF6 as electrolyte) by stepping the potential of a Pt disk working electrode between potentials sufficient to form the radical anionic and cationic species. The relative amount of light produced during the anodic and cathodic pulses was dependent on the potential limits and pulse duration. ECL was also generated in the presence of coreactants, i.e., with tri-n-propylami...

TL;DR: In this article, a dendrimer with a fluorescent core consisting of a rubicene moiety is synthesized and the hydrodynamical volume is determined in toluene, a good solvent, acetone, a medium quality solvent, and acetonitrile, a poor solvent.
Abstract: Four generations of a dendrimer with a fluorescent core consisting of a rubicene moiety are synthesized. The biexponential nature of fluorescence decay in toluene indicates the presence of two emitting conformations. Molecular modeling suggests that a conformation where the dendrons interact with the core is not improbable. The relative weight of the two decay times indicates that the contribution of that conformation in toluene increases as the dendrimer generation increases. In acetone and acetonitrile however the fluorescence decay is, except for the fourth generation, monoexponential. The hydrodynamical volume of the dendrimer is determined in toluene, a good solvent, acetone, a medium quality solvent, and acetonitrile, a poor solvent, with the time-resolved fluorescence depolarization technique. No change of the hydrodynamical volume is found in toluene in a temperature range between 20 and 94 °C. This suggests that the dendrimers of all the generations are fully expanded in this solvent. In acetonit...
