13. In order to obtain critical distance criteria for the energy transfer processes, we employed the fully extended molecular models, wherein all equivalent dendrimer units should be arranged at the same distances from the perylene core in identical orientation

19. For energy transfer dynamics, time-resolved fluorescence measurements have been performed on the dendrimers. However, attempts to record fluorescence decays failed due to the limited time resolution of the experimental setup (100 ps response time)
