Correlation between the structure and biological activity studies of supramolecular coordination azodye compounds

 A series of novel bidentate azodye quinoline ligands were synthesized with various 
p-aromatic amines like p-(OCH 3, CH 3, H, Cl and NO 2). Novel azodye (HL n) and 
complexes [Cu (II)/Ni (II)] of these ligands have been characterized on the basis of elemental 
analysis, molar conductance and magnetic measurements, infrared and electronic spectral 
studies. Suitable structures have been proposed for these complexes. The synthesized 
ligands and their metal complexes were screened for their antimicrobial activity against four 
local bacterial species, two Gram positive bacteria (Bacillus cereus and Staphylococcus 
aureus) and two Gram negative bacteria (Escherichia coli and Klebsiella pneumoniae) as 
well as against four local fungal species; name
