Zusammenfassung
The synthesis, structure, photophysics, and spectroscopic characterization of two novel organometallic rhodium and rhenium multichromophore photosensitizers carrying a central 2,2'-bipyridyl acceptor moiety are reported. Due to the presence of rigid phenylethynyl substituents in their 5,5'-position acting as intramolecular antenna groups, these compounds display perturbed excited state properties and a modified luminescence behaviour compared to the unsubstituted parent systems. The rhodium derivative is characterized by a weak blue-green intraligand (IL) phosphorescence occurring only at low temperatures. In the rhenium complex both a blue-green ligand-based luminescence and a red phosphorescence of metal-to-ligand charge transfer (MLCT) origin is observed at room temperature in solution. In rigid 77 K matrix the lowest-lying excited state levels approximate in energy and a structured luminescence band occurs which is ascribed to a ligand phosphorescence with admixed MLCT character.
