    • Abstract

       

      In this study, a new imine-based tripodal ligand and its difluoroboron complex were designed and synthesized. This trinuclear-boron complex was prepared for the first time and fully characterized by common spectroscopic techniques such as 1H-NMR, 13C-NMR, FT-IR, UV–Vis and MS analysis. The optical and fluorescence properties of complex were examined in CHCl3, THF, acetonitrile, EtOAc, DMF and DMSO. It was revealed that the obtained boron complex showed intense emission with large Stokes shifts in the range from 83 nm to 96 nm. As a result of quantification of fluorescence quantum yields, it has been observed that it has high quantum yield values up to 48%. The large Stokes shifts and high efficient emissions in the solutions of boron complex make it precious fluorophore for potential applications in materials science
