A highly emissive cruciform triarylborane as a ratiometric and solid state fluorescence sensor for fluoride ions

摘要: Abstract We disclosed a novel cruciform tri-coordinate organoboron compound, 2′,5′-bis{[(4-dimesitylboryl)phenyl]ethynyl}-1′,4′-bis[(4- N , -diphenylamino)phenyl]-[1,1′:4′,1′]terphenyls, which displays characteristic intramolecular charge transfer transition and is highly emissive both in solutions solid state. The complexation with fluoride ions induces large blue shift fluorescence, enabling ratiometric fluorescence sensing of fluoride. In addition, its prompt response to was also observed even the
