gs as measured by DSC for the polymers employed in this study, PiBMA and PEMA, were unchanged by the low level of labeling or doping with chromophores; therefore, the introduction of the fluorescent chromophores at low levels does not significantly affect polymer dynamics in these systems. Thus, the dopant chromophores can be considered as diffusing from one film, of infinitesimal chromophore content, to another of zero concentration. Consequently, it can be assumed that the layered films used in this study constitute a continuous matrix through which the donor molecules diffuse.
