摘要：

Several spectroscopic properties of pyrene and its derivatives dissolved in polymer films were examined to investigate the microstructure of polystyrene-poly(2-vinylpyridine) diblock copolymer. Both the fluorescence vibronic structure (I1/I3) and fluorescence lifetimes of several of these probes are quite useful as indicators of the polarity of microdomains in the polymers. This finding was applied to study the microstructure of the diblock copolymer film. The results indicate that PS and PVP chains of the copolymer are not randomly mixed but are phase separated, as expected.
