Ouadoudi, O., Kaehler, T., Çevik, E., Bolte, M., Stöger, B., Virovets, A., Lerner, H.-W., & Wagner, M. (2022). Late-stage derivatization of a (B,O)2-doped perylene. Dalton Transactions, 51(35), 13195–13198. https://doi.org/10.1039/d2dt02364d
Regioselective di- and tetrabrominations of the (B,O)2-perylene 1 afford derivatives 2-4. Despite their poor solubility, 2 and 4 could be used in Stille-type coupling reactions to introduce two CCMe (5) or four CC(p-C6H4tBu) substituents (6), respectively. The alkynylated derivatives show blue-green photoluminescence with appreciable quantum efficiencies.
