摘要：

Difluoroboron dibenzoylmethanepoly(lactic acid) emission is sensitive to the polarity of the surrounding medium. As the polymer molecular weight increases, fluorescence maxima blue-shift for these dye-polymer conjugates. A similar shift is noted in their delayed emission spectra. This "green to blue" color change may be attributed to decreasing fluorophore-fluorophore interactions and polarity with increasing polymer molecular weight.
