(A) Illustration and chemical structure of chiral BNPh₂-BNaph. (B) CPL (top) and fluorescence (bottom) spectra of BNPh₂-BNaph in cyclohexane (blue) and MeCN (red), condition: 1.23 × 10⁻⁴ M, λ_ex = 340 nm. (C) CPL (top) and fluorescence (bottom) changes of BNPh₂-BNaph upon addition of F⁻ (tetrabutylammonium fluoride, 20 equiv). The measurements were carried out in THF solution (~1.23 × 10⁻⁴ M), under the excitation of 320 nm. Reproduced with permission (Sun Z. et al., 2019). Copyright 2019, John Wiley and Sons.
