Hexa-peri-hexabenzocoronene/perylenedicarboxymonoimide and diimide dyads as models to study intramolecular energy transfer

Star-like and butterfly-shaped dyads based on hexa-peri-hexabenzocoronene (HBC) as donor and perylenedicarboxymoniimide (PMI) or diimide (PDI) as acceptor were synthesized and the intramolecular energy/electron transfer was investigated by steady-state fluorescence spectroscopy.
