Abstract

The excimer formation of 1-pyrenylpentametyldisilane (P2) in isooctane is studied as a function of concentration and temperature. This contribution shows for the first time how the global compartmental analysis can be used to determine the temperature dependence of the excited state processes of an excimer forming species, i.e. the activation energy of excimer formation and excimer dissociation, the stabilisation enthalpy of the excimer (DELTAH-degree) and the entropy change of the excimer formation. The activation energy of excimer formation is found to be larger than the activation energy for viscous flow.
