Dynamical arrest of electron transfer in liquid crystalline solvents

Article Abstract:

The energetics of electron transfer (ET) reactions in liquid crystalline solvents both in their isotropic and nematic phases is studied. The energy gap law of electron transfer reactions in slowly relaxing solvents is characterized by regions of fast change of the rate at points where the reaction switches between the ergodic and nonergodic regimes and the energy dependence of the rate on the donor-acceptor separation might be affected in a way of producing low values for the exponential falloff parameter.

Reorganization energy of electron transfer in viscous solvents above the glass transition

Article Abstract:

A molecular-dynamics study of solvent reorganization energy of electron transfer in supercooled model is presented. The results revealed a sharp decrease of the reorganizational energy at a temperature identified as the temperature of structural arrest due to cage effect as discussed by the mode coupling theory.
