Fluorescence and Theoretical Calculation of Phenylhydrazone Derivatives and Fluorine Boron Complex: Synthesis and Fluorescence Characteristics

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.

Synthesis and antifungal activity of 1,2,3-triazole phenylhydrazone derivatives

A series of 1,2,3-triazole phenylhydrazone derivatives were designed and synthesized as antifungal agents.
