“…Lifetimes as a function of temperature were measured for [Re(bipy)(CO),CI] and [Re(bipy)(C0),(4-Etpy)] +. For the temperature dependence near room temperature, the data could be fitted to equation (6) where k, is the Boltzmann constant, which is appropriate for two nondegenerate states with a contribution to decay coming from an upper, non-emitting state.36 In the underlying kinetic model which leads to equation (6), the term ko is the Boltzmann averaged value of the decay rate constant from the low-lying, * Estimated errors are he, (77 K) k 2 nm, he, (295 K) _+ 5 nm, qem k lo%, z f 2%, -t 3 ns for the final three entries. hmaX,,, is the emission maximum and qem the quantum yield for emission.…”

“…In a previous paper we showed that temperature-and pressure-controlled experiments provided complementary results on the solvent-assisted relaxation dynamics of Ru(II) complexes. 4 In solid state, on the other hand, the reorganization of molecular environment is unlikely since the motion of the surrounding molecules is prevented. Therefore, both intramolecular factors (overlaps of atomic orbitals, distortion of bond angles, change in interatomic distance, and so forth) and intermolecular factors (morphology, crystal structure, intermolecular distance and orientation, and so forth) are major parameters to decide the excited properties.…”
