Abstract: The Boron atom has seen an increase in usefulness over the last half
century due in part to the unique properties of boron that allow for dative binding.
Aspects of the boron-nitrogen bond were examined through both displacement
reactions, which were monitored by NMR, and photoluminescence studies done
with a Fluorometer. Through the NMR study it was discovered that the dative
bond is affected by both the electronic configuration of the boroxine and the pKa
of the Lewis base being used for complexation. It appears that the displacement of
pyridine from the original complex is dictated by the pKa of the displacing base; a
stronger base leading to more complete displacement of pyridine from the
complex. Using fluorimetry, several Lewis base-boroxine complexes were studied
in order to observe possible differences in the ?max emission between the
uncomplexed boroxine and the coupled base-boroxine pair, a behavior believed to
be dependent on the shifting of electron density from the Lewis base towards the
boroxine.
