Two BN-embedded benzo[ghi]perylene and coronene derivatives have been synthesized and their properties show significantly enhanced absorption and emission compared to their all carbon analogues. BN-Cor has a fluorescence quantum yield nearly 20 times higher than ordinary coronene.
Two BN-embedded benzo[ghi]perylene (Bzp) and coronene derivatives (BN-Bzp and BN-Cor) have been successfully synthesized from binaphthyl precursors by new efficient one-pot-multibond routes, and their single crystal structures were analyzed. Both experimental spectra and DFT theoretical calculations indicated that the absorption and emission of these BN-embedded polycyclic aromatic hydrocarbons are significantly enhanced comparing with those of their all carbon analogues. Especially, the fluorescence quantum yield of BN-Cor is nearly 20 times higher than that of ordinary coronene.
