摘要
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.
