A sereis of phenylhydrazone-based derivatives and their corresponding BF2 complexes were synthesized efficiently by a three-step reaction. Photophysical performance was investigated in different organic solvents and in the solid state. Although these compounds exhibited feeble fluorescent intensity in solution-state, BF2 complexes showed weaker fluorescence in solid state compared to precursors 2, which were caused by slight geometry relaxation of upon photo excitation. Density Functional Theory calculations was carried out to confirm above inference.
