In this study, it is
aimed to obtain of N,N’-Bis(3-tert-Butyl-5-methylsalicylidene)-1,2-diaminoethane-boron
complex (3) in three-step reaction. In
the first step, an aromatic aldehyde derivative was synthesized by the
o-formylation reaction with commercially available an aromatic phenol. The condensation
reaction was carried out to give the imine derivative as a Schiff base ligand (2). The fluorine chelated boron complex
was synthesized through the reaction of BF3.OEt2 with
ligand (2). This Schiff base-boron
complex was reported for the first time and was fully characterized by common
spectroscopic techniques such as 1H-NMR, 13C-NMR, FT-IR,
UV–Vis, MS and elemental analysis. The spectroscopic properties of the target
boron-complex were examined with the absorption and fluorescence spectroscopy. It
was determined that the obtained boron complex is highly emissive molecule in
different solvents with large Stokes shifts reaching 100 nm. Moreover, the
measurements of the fluorescence quantum yields (up to 48%) were performed.
