摘要：
Nonradiative energy transfer fluorescence was used to investigate the micelle behavior of polystyrene-b-poly(ethylene oxide) diblock copoly- mers tagged with either donor naphthalene or acceptor pyrene in solutions and solid films. The effects of the variation in the solvency and micelle collision frequency caused by changing the total block copolymer concentration and the difference in the micelle concentration between polystyrene-poly(ethylene oxide) block copolymers labeled with two different chromophores on the chain release and exchange of micelles were observed. it was noted that the chain exchange of the polymer micelles is clearly observed when the concentration difference and the total micelle concentration are sufficiently large. in the case of the solid film, the NRET efficiency is increased as the molecular weight of the matrix polystyrene homopolymer added is increased.
