By combining two special structural units, a novel BN aromatics, BN-Az, has been designed and synthesized with unique characteristics. BN-Az selectively responds to fluoride ions and protons with a significant color change, indicating its potential as an effective ion sensing material in stimuli-responsive electronic devices.
Main observation and conclusion By combination of two special structural units, a boron-nitrogen-fused polycyclic aromatic hydrocarbon and azulene with strong intramolecular dipoles, a novel BN aromatics, BN-Az, has been designed and synthesized with unique characteristics. The structure, optical and electrochemical properties, as well as charge transport property of BN-Az have been investigated. Notably, BN-Az selectively responds to fluoride ions and protons with a significant color change, which could also be monitored by NMR spectra and single-crystal X-ray analysis, indicating its potential as an effective ion sensing material in stimuli-responsive electronic devices.
