摘要：

The relative diffusion between polymer chain ends during donor excitation lifetimes has been shown to increase the energy-transfer efficiencies experimentally observed between energy donor and acceptor groups attached at the ends of polymer chains. The relative diffusion of the end groups has also been shown to alter both donor and acceptor fluorescence decay curves. The feasibility of using these techniques for experimental measurement of relative diffusion coefficients of polymer chain ends is discussed. © 1990, American Chemical Society. All rights reserved.
