โœฆ Synopsis

An intramolecular electron transfer compound (4-(10-cyano-9-anthracenylmethyl)-N,N-dimethylaniline) has been studied under different pressure up to about 6 GPa. The electron transfer (ET) rate constants (k et ) with pressure have been obtained from its fluorescence emission and decay processes at different pressures. By analogy with the theory of optical transition, the free energy change (DG) and solvent reorganization energy (k) during the ET process can be expressed by the functions including the variable pressure. The experimental results can be understood well by analyzing the influence of DG and k on the k et with pressure.

The intramolecular electron-transfer state of 9.9'-bianthryl was investigated in viscous solvents at high pressures. In the low-pressure region, there is a true equilibrium between the electron transfer and locally excited states, whereas the increase in the viscosity of the solvents becomes the dom
