Energy transfer in multichromophoric self-assembled molecular squares.
Metal-ion directed self-assembly afforded well-defined molecular squares with a mass of 12 kDa incorporating four perylene bisimide and sixteen pyrene chromophores organized in a circular way. Energy transfer from the pyrene to the perylene dye manifold is investigated by emission and excitation spectroscopy.
