Studies On Synthesis,Characterization And Supramolecular Structure Of Some Phenylhydrazones

Modern Chemistry manifests that the properties and functions of chemical substances are depondent on not only the component molecules, but also the structure beyond the molecular level, which develops a new branch ofchemistry——supramolecular chemistry. Phenylhydrazone derivatives havepotential application in biochemistry, medicine and materials science.This thesis focuses on supramolecular structures of phenylhydrazone derivatives,especially on intermolecular hydrogen bonding and aromatic n-n -stacking interaction.A series of phenylhydrazone derivatives were synthesized by reacting varieties of carbonyl compounds(aldehydes and ketones) with 2,4-dinitrophenyl hydrazine and 4-nitrophenylhydrazine respectively, and thirteen single crystals (never reported before) were determined by single crystal X-ray diffraction (see the table below).
