Photoprocesses in stilbene-based bifluorophores

Pyrene−Indole Exciplexes as Positive Photocatalysts

“…Bichromophoric compounds have attracted considerable interest during the last decades. They have been used as models for the study of a variety of processes, including (i) drug photobinding to proteins, lipids, and nucleic acids, (ii) photoinduced electron and energy transfer as well as its implications in photosynthesis, development of molecular devices, etc., and (iii) chiral recognition in the intramolecular interactions in the excited state . They have also found application as ultraviolet stabilizers, to avoid UV degradation of organic compositions (such as polymers), and as effective systems for photodynamic therapy. , …”
