摘要：A simple 1,1'-bi-2-naphthol (1,1'-BINOL) boron complex has been rationally designed and synthesized, the structure of which was confirmed by single crystal X-ray diffraction analysis. Furthermore, the complex exhibited turn-on fluorescence for fluoride ions with high selectivity and sensitivity. The recognition mechanism for promoting was determined by H-1, F-19 and B-11 NMR titrations, which indicated that both the photo-induced electron-transfer (PET) and the intramolecular charge transfer (ICT) effects were functionalized. In addition, the complex showed strong solid-state fluorescence, and the emission spectrum and quantum efficiency (OF) of the solid powders were also measured. (C) 2016 Elsevier Ltd.
