    • 0 arises because the oscillator strength of the cyanine dye absorption increases with conjugation length (see Table 1) and this effect partially compensates for the decreased wavelength matching of the polymer's fluorescence with the dyes' absorption bands.

    • If this model for the PPESO3 aggregate is correct, the ionic face of the aggregate is very similar to the surface of an ionic material, for example, a clay surface or silver halide crystal. Such ionic surfaces are known to template the formation of J-aggregates, see refs 51 and 53.
