Abstract
- Time-resolved fluorescence depolarization is used to examine electronic excitation transport among naphthalene chromophores in a polymeric solid as a function of excitation wavelength between 300 and 50 K. The characteristics of the wavelength and temperature dependences reveal, for the first time, that dispersive transport occurs at and near room temperature. The rate of excitation transport depends on the wavelength of excitation. A theoretical treatment is able to reproduce the essential features of the wavelength and temperature dependences without recourse to adjustable parameters by avoiding the complexities of the relationship between the difference in energy of a pair of molecules and the pairwise transfer rate.
