Double Properties of Novel Acylhydrazone Nanomaterials Based on a Conjugated System: Anion Binding Ability and Antibacterial Activity

A series of new compounds (1–12) containing 1,5-diaza-fluorenone, 1,10-phenanthroline-5,6-dione, ferrocene-1,1ʹ-dione, anthracene-9-carbaldehyde have been synthesized and optimized. The nanomaterials were also developed successfully. The binding properties were evaluated for biologically important anions (F−, Cl−, Br−, I−, AcO−, and H2PO4−) by theoretical investigation, UV-vis, and fluorescence experiments, and compound6displayed the strongest binding ability for AcO−ion among the synthesized compounds. Theoretical investigation analysis revealed that the intramolecular hydrogen bond existed in the structure of compound6and the roles of molecular frontier orbitals in molecular interplay. In addition, compound6showed wide antibacterial activity for colon bacillus, typhoid bacillus, andPseudomonas aeruginosa, and inferior activity for hay bacillus andStaphylococcus aureus. This series of acylhydrazone nanomaterials showed double properties, anion binding ability, and antibacterial activity.Keywords:binding ability;antibacterial activity;acylhydrazone derivative;nanomaterials;synthesis
