BN-acenes, where a B-N bond replaces a C horizontal lineC bond, display modified optical and electronic properties compared with the parent acenes. Twisting acenes is an additional strategy to modify their photophysical and electronic properties. However, attempts to twist linear BN-acenes have not been reported. In this study, we employed computational tools to investigate the thermodynamic and electronic characteristics of twisted BN-anthracenes. Our findings indicate that the position of the nitrogen atom within the carbon skeleton is crucial for reducing strain energy and that a greater tuning of the HOMO-LUMO gap is achievable for BN-acenes compared to their all-carbon analogue.
