A BN anthracene mimics the electronic structure of more highly conjugated systems

Dalton Trans. 2019 Feb 19;48(8):2807-2812. doi: 10.1039/c9dt00481e.

Abstract

9a,9-BN anthracene was synthesized using a simple three-step sequence involving intramolecular electrophilic borylation of 2-benzylpyridines. The same procedure can be applied to yield a number of substituted 9a,9-BN anthracenes. Spectroscopic characterization of the parental compound (UV-photoelectron spectroscopy, UV-vis absorption/emission) shows an electronic structure more similar to that of a larger conjugated system rather than anthracene, the direct all-carbon analogue.
