Synthesis And Characterization Of A Bn-Embedded Nine-Ring Fused Heteroaromatics With Dual Channel Detection Of Fluoride Anions

Polycyclic aromatic hydrocarbons (PAHs), especially acenes, have been studied extensively because of the unique chemical structures, optoelectronic properties as well as widespread application. Introducing heteroatoms can finely tune the optoelectronic properties and improve the stability and solubility of acene derivatives, thus broadening their potential applications. In this study, an anthradithiophene-based BN-embedded heteroaromatics with nine fused rings (ADTBN) and two trialkylsilylethynyl groups is designed and synthesized, which exhibits excellent stability and solubility. The optoelectronic properties and fluoride susceptibility of ADTBN have been comprehensively studied. ADTBN shows selective and sensitive dual channel turn-off fluorescence for fluoride anion, and we reveal that it could be a potential candidate for sensors.
