  The nature of 6,6′-bis(triphenylamine) substituted BINOL as chromophoric and fluorogenic hybrid chemosensor for selective fluoride detection

  摘要：

  6,6'-Bis(triphenylamine)-1,1'-binaphthy1-2,2'-diol (1) is highly fluorescent in visible region. On treatment with a variety of anions, the UV-vis absorption as well as the fluorescent behavior of 1 in CH2Cl2 is substantially changed. Among the tetrabutylammonium (TBA) salts we tested, including F- OH- (from TBAOH in MeOH), Cl-, Br-, I-, OAc-, HSO4-, TsO- (Et4N salt), and H2PO4-, F- was found to be the most effective fluorescence quencher. Quantitative fluorescence analysis of the titration data revealed that the anions are classified into two categories: (1) Simple mono-anions, such as F- (log beta(F)(2) = 11.00 +/- 0.08), OH- (log beta(OH)(2) = 9.05 +/- 0.01), and Cl- (log beta(2) = 9.96 +/- 0.70) that follow the stoichiometry of 1:2, indicating the formation of (1.X-2)(2-) complexes; (2) Oxo-anions, such as OAc- (log beta(OAc)(1) = 5.13 +/- 0.012), H2PO4- (log beta(HP)(1) = 4.87 +/- 0.03), and TsO- (using tetraethylammonium salt, (log beta(OTs)(1) = 3.36 +/- 0.02) that show the stoichiometry of 1:1, indicating the formation of (1.X)(-) complexes. The complexation behaviors were further confirmed by H-1 NMR spectroscopy. In the co-crystal prepared from 1,1-binaphthy1-2,2'-diol (BINOL) and Et4NF, F- and BINOL are assembled to form a linear polymeric array, with a dimeric group of BINOL/BINOL anions linked as the side-chains. Intramolecular hydrogen bond was observed within the BINOL anion. This provides structural insights about the BINOL-fluoride complex formation. (C) 2011 Elsevier Ltd. All rights reserved.
