Paper Abstract

The nonlinear energy dynamics of a glassy donor-acceptor two-photon dye, AF-455, is investigated using ultrafast nonlinear spectroscopy. This material is of interest as a model system to examine concentration dependencies on the nonlinear behavior in processing from a dilute liquid state to a viscous glassy state. It is believed that due to the extended molecular structure compared to the typical dipole-dipole energy transfer critical interaction distances, that high (neat) concentrations will have little impact on the nonlinear response of the molecules. Experimental and theoretical considerations of the electronic dynamics are discussed using a rate analysis for comparison. Speculation of the charge generation of the system is also presented.
