A series of multicolor fluorescent N,O-bidentate BF2 complexes with variable ligand structures have been synthesized. These complexes exhibit the solvent-independent optical properties and large Stoke shifts. The electrochemical measurements demonstrate that all these chelates are better electron acceptors than the commonly used material Alq3. A qualitative structure–property relationship among these
