title: An artificial antenna complex containing four Ru(bpy)3(2+)-type chromophores as light-harvesting components and a Ru(bpy)(CN)4(2-) subunit as the energy trap. A structural motif which resembles the natural photosynthetic systems.
abstract: A cyclam subunit bearing four light-harvesting Ru(bpy)3(2+)-type species is connected to a Ru(II) compound having low-lying excited states (energy trap) by hydrogen bonding: the light absorbed by the light-harvesting elements is funnelled to the energy trap with high efficiency.
