Abstract: Understanding the nature of photoinduced processes in organic molecules is essential for the design and synthesis of compounds with desired photochemical properties. This dissertation aims for gaining knowledge and mechanistic understanding of energy transfer in perylene-based systems. The investigations were performed using isomeric Donor-bridge-Acceptor systems, where perylene was used as an acceptor. Identifying the correlations between the molecular structure of the dyads and their photo... more
