Fluorescence depolarization by energy migration: Energy migration between individual oligo-phenylene-ethynylenes pendant to a polymer backbone as well as energy transfer from blue-emitting donors to red-emitting acceptors (see picture) is investigated by means of fluorescence emission spectroscopy. Emission anisotropy measurements indicate fluorescence depolarization due to energy migration.
