| Outline of Final Research Achievements |
We found that thermal deactivation of phosphorescent states in platinum (II) complexes was remarkably suppressed in rigid organic glasses and most of the complexes exhibited highly efficient phosphorescence in polymers. To elucidate the strong rigid media effects, thermal deactivation pathways of phosphorescent state in various platinum (II) complexes have been studied by measuring the activation energy and activation volume of the deactivation processes and by comparing them with those predicted by DFT calculations. It was revealed that the thermal deactivation involves transition states with peculiar structures, which is responsible for the remarkable rigid media effects of phosphorescent states in platinum (II) complexes.
