Abstract :
The paper focuses on a novel approach to reveal ultrafast dynamics in single molecules. The main strength of the approach is towards ultrafast processes in extended multi-chromophoric molecular assemblies. Excitonically coupled systems consisting of 2 and 3 rigidly linked perylene-diimide units in a head to tail configuration are studied. Superradiance and inhibited intramolecular decay are observed and discrete jumps in femtosecond response upon break-up of the strong coupling are revealed.
