Photochemical charge separation within aromatic hydrazines and the effect of excited-state intervalence in dihydrazines.
Photolysis into the longest wavelength absorption band of 2-tert-butyl-2,3-diazabicyclo[2.2.2]oct-3-yl hydrazine (Hy) substituted naphthalenes causes aryl group reduction electron transfer to give (+)Hy-Ar(-). Electrooptical absorption measurements characterize the charge separation properties from these bands. Emission studies demonstrate that the separation between absorption and emission max...

متن کاملNonequilibrium charge recombination from the excited adiabatic state of donor-acceptor complexes.
A model of nonequilibrium charge recombination from an excited adiabatic state of a donor-acceptor complex induced by the nonadiabatic interaction operator is considered. The decay of the excited state population prepared by a short laser pulse is shown to be highly nonexponential. The influence of the excitation pulse carrier frequency on the ultrafast charge recombination dynamics of excited ...
متن کاملUltrafast excited state absorption and charge separation in phenylene-based conjugated polymers
Ultrafast pump-probe spectroscopy of phenylene-based -conjugated polymers give low and high energy photoinduced absorptions (PAs) to final states with very different relaxation behavior. While the low energy two-photon state that is reached in PA relaxes to the optical exciton in ultrafast times, the higher energy two-photon state violates the Vavilov–Kasha rule and instead of relaxing to the o...
