摘要：

Electronic dipole-dipole energy transfer between perylene molecules and from perylene to cobalt(II) ions has been observed in lipid bilayers below the gel to liquid-crystalline phase transition. It is shown that due to clustering donor-donor energy transfer has to be taken into account at the low acceptor concentrations when analysing the fluorescence decay data in terms of Forster kinetics. This correction then gives an interaction radius for energy transfer from perylene to Co2+ of almost-equal-to 13.4 angstrom, which is comparable to the theoretical value and also to that found in glycerol.
