| Abstract: | Two types of novel BF2 complexes are readily obtained by the reaction of BF3OEt with 3-(2-oxo-2-arylethylidene)-3,4-dihydro-1H-quinoxalin-2-ones or 3-(2-oxo-2-arylethylidene)-3,4-dihydrobenzo1,4]oxazin-2-ones, respectively in refluxing acetic acid/toluene solvent mixture. The complexes are confirmed by elemental analysis, FT-IR, 1H, 13C, 11B, 19F NMR and one of them is executed its X-ray crystallographic study. The outstanding photophysical properties of these complexes are determined by UV–vis absorption and fluorescence emission spectroscopy. |
