A series of 8 luminescent borafluorene complexes were extensively studied both experimentally and theoretically in order to elucidate the effect of organoboron moiety rigidification on the physicochemical properties of these compounds. Due to the spiro ge

The reaction of 8-hydroxyquinoline (HQ) with B(C6F 5)3 leads to the formation of the zwitterionic compound (C6F5)3BQH (1), involving a proton migration from O to N. Compound 1 can be converted thermally to (C6F 5)2BQ (2), which can also be prepared from (C 6F5)2BCl and HQ. The reaction of HQ with (C6F5)B(OC6F5)2 generates initially (C6F5)(OC6F5)BQ (3), which easily hydrolyses to give the diboron compound ((C6F 5)BQ)2O (4). Compounds 1, 2 and 4 have been fully characterised, including X-ray analysis. The spectroscopic properties of these compounds, including photoluminescence (PL) have been investigated and compared with the non-fluorinated luminescent boron compound (C6H 5)2BQ and also with AlQ3. The changes in luminescent behaviour upon fluorination of these boron quinolinate compounds have been rationalised using computational studies. The Royal Society of Chemistry.
