Energy migration between trimeric oligo-phenylene-ethynylenes pendant to poly-methyl-metacrylic polymers causes a fast decay of fluorescence anisotropy after selective excitation by linearly polarized laser pulses. The excitation energy finally is trapped by a brigthly fluorescent acceptor dye, as shown on p. 170 by B. Dietzek et al.
