摘要: Abstract The fluorescence decays of 1,3-di(1-pyrenyl)propane undergoing intramolecular excimer formation can be fitted to a sum three exponentials, whereas only two exponentials are needed for 1,3-di(2-pyrenyl)propane. It is concluded, from an analysis the decay parameters, that one monomer and excimers involved in 1,3-di(1-pyrenyl)-propane, contrast with 1,3-di(2-pyrenyl)propane where kinetic scheme. Kinetic thermodynamic data presented both molecules. significance various cases (double higher) multi-exponential discussed.
