The results from simulations of charge and energy dynamics in poly(para-phenylenevinylene) (PPV) and PPV interacting with C60 were reported. The time-dependent Schrödinger equation and the lattice equation of motion simultaneously and nonadiabatically solved for performing these simulations. The electronic system and the coupling of the electrons to the lattice were described by an extended three-dimensional version of the Su-Schrieffer-Heeger model. The simulation of electron and lattice dynamics following an electronic excitations at different energies was also presented. The results show that both exciton diffusion and transitions from high to lower lying excitations were stimulated by increasing the lattice energy.
