Synthesis and Fluorescence Properties of Novel Pyrazine–Boron Complexes Bearing a β-Iminoketone Ligand


A novel fluorescence dye based on pyrazine–boron complexes bearing a β-iminoketone ligand has been synthesized by using a simple two-step reaction. Synthesized complexes exhibited fluorescence in solution (<i>F</i><sub>max</sub>: 472–604 nm) and in the solid state (<i>F</i><sub>max</sub>: 496–624 nm). These complexes showed a larger Stokes shift (3690–4900 cm<sup>–1</sup>) than well-known boron dipyrromethene dyes (400–600 cm<sup>–1</sup>, in most cases)
