Keywords:Triazine,o-hydroxyacetophenone,fluorescence, SHG, Antimicrobial activity.
A novel design of triazine based ligand with o-hydroxyacetophenonenucleus (L) has been synthesized. A series of metal(II) complexes of general formula [ML.H2O][where M = Cu(II), Ni(II), Co(II) and Zn(II)] have been obtained.UV-Visible, magnetic susceptibility, Infrared, 1H NMR, Mass and electron spin resonance (ESR) techniques have been used to elucidate the structures of metal complexes. Spectroscopy and other data show octahedral geometry for metal(II) complexes. The fluorescence spectra of all the complexes revealed the photoactive nature of the complexes. The ligand was found to exhibit better second harmonic generation (SHG) efficiency compared to that of urea and KDP. The ligand and its metal complexes were screened for their antibacterial and antifungal activities. This study revealed the increased antimicrobial activity exhibited by the than the ligand.
