None:
A family of bidentate boron complexes based on a 2,1-borazaronaphthalene scaffold, containing both tri- and tetracoordinate boron centers, were synthesized. These complexes exhibit tunable absorption-emission and solid-state fluorescence, accompanied by large Stokes shifts (4100-9200 cm-1) due to intramolecular charge transfer. Notably, binding of fluoride at the tricoordinate boron center triggers distinct colorimetric and fluorometric responses with a high association constant (Ka ≈ 3 × 104 M-1), which highlights their potential for fluoride detection.
