Abstract
The intralayer and interlayer aggregation of octadecylrhodamine 6G mix ed in a stearic acid matrix have been studied by flash photolysis and picosecond fluorescence methods in Langmuir-Blodgett films. Both intra layer and interlayer dimers relax via their triplet state. The dominan t fluorescence quenching process is either excimer formation or cluste r fluorescence. The activation energy of excimer formation is 3.8 kJ m ol-1.
