3-(1-Alkynyl)perylenes undergo oxygenation when subjected to irradiation with visible light under aerated conditions. The structures of novel oxygenated products formed in this manner are assigned as regioisomeric dibenzo[jk,mn]phenanthrene-4,5-diones.

- Researchers created DNA-like fluorescent oligomers using alkynyl beta-D-ribofuranosides with different fluorophores like pyrene, perylene, and anthracene via solid-phase synthesis.
- These fluorescent oligomers are designed to have a specific arrangement of fluorophores, allowing them to interact closely through hydrophobic forces.
- Both homooligomers and heterooligomers showed strong excimer emissions in water, indicating effective energy transfer between the fluorophores in various combinations.
