Harvesting sunlight by artificial supramolecular antennae
Solar Energy Materials and Solar Cells, 2000Co-Authors: Vincenzo Balzani, Sebastiano Campagna, Gianfranco Denti, Alberto Juris, Scolastica Serroni, Margherita VenturiAbstract:Abstract We have designed a divergent synthetic strategy, based on the “complexes-as-metals and complexes-as-ligands” procedure, to prepare Polynuclear metal Compounds of nanometer size and dendritic structure. Such a synthetic strategy is modular, very flexible, efficient, and characterized by a full, step-by-step control of the growing process. It allows us to obtain supramolecular arrays where different metal ions, bridging ligands, and terminal ligands can occupy predetermined sites. In this way, the light absorption, luminescence, and redox properties of these Polynuclear Compounds can be varied. In particular, it is possible to obtain a synthetic control of the direction(s) of electronic energy transfer after light absorption. This is a step towards the construction of nanometer-sized antennae for harvesting solar energy.

Bottom-up strategy to obtain luminescent and redox-active metal complexes of nanometric dimensions
Coordination Chemistry Reviews, 1994Co-Authors: Vincenzo Balzani, Sebastiano Campagna, Gianfranco Denti, Alberto Juris, Scolastica Serroni, Margherita VenturiAbstract:Abstract By using the “complexes as metals and complexes as ligands” synthetic strategy, it has been possible to obtain oligonuclear metal complexes which contain up to 22 metal ions. Complexes containing two different types of metal ions (Ru and Os; Ru and Rh; Os and Rh; Ru and Ir) have also been prepared. The light absorption, luminescence, and redox properties of these Polynuclear Compounds can be varied by changing (i) the nuclearity, (ii) the nature of metal ions, bridging ligands and/or terminal ligands, and (iii) the position of the various components in the supramolecular structure. Because of their strong absorption in the visible spectral region and the possibility to predetermine the direction of energy migration, these Compounds could be used as photochemical molecular devices for harvesting solar energy.

Supramolecular photochemistry. Luminescent and redox active dendritic Polynuclear metal complexes
Journal of Chemical Sciences, 1993Co-Authors: Vincenzo Balzani, Sebastiano Campagna, Gianfranco Denti, Alberto Juris, Scolastica Serroni, Vittorio RicevutoAbstract:The synthetic strategies used to prepare di-, tri-, tetra-, hexa-, hepta-, deca-, trideca- and docosanuclear Ru(II) and/or Os(II) polypyridine-type complexes containing the 2,3-dpp and/or 2,5-dpp bridging ligands and the bpy and/or biq terminal ligands are described (dpp = Bis(2-pyridyl)pyrazine; bpy = 2,2’-bipyridine; biq = 2,2’-biquinoline). The light absorption, luminescence, and redox properties of these Polynuclear Compounds can be varied by changing (i) the nuclearity, (ii) the nature of metal ions, bridging ligands and/or terminal ligands, and (iii) the position of the various components in the supramolecular structure. Because of their strong absorption in the visible spectral region and the possibility of predetermining the direction of energy migration, these Compounds can be used as photochemical molecular devices (e.g., as antennas for harvesting solar energy). Because of the presence of several interacting and/or noninteracting redox centres, they are good candidates to play the role of multielectron-transfer catalysts.
