The Effect of Electron-withdrawing Group Functionalization on Antibacterial and Catalytic Activity of Palladium(II) Complexes

] (2), [HL1 = 2-((E)-(2,6-diethylphenylimino)methyl)-4,6-dibromophenol, L2 = (E)-N-benzylidene-2,6-diethylbenzenamine], which are obtained by functionalizingSchiff base ligands with or without electron-withdrawing groups. Both compounds are mononuclear structures.Comparisons are made to the compounds 1 and 2 to analyze and understand the effect of electron-withdrawinggroups. Antibacterial activity studies indicate the electron-withdrawing groups on Schiff base ligands enhanceantibacterial activity. Catalytic activity, however, is reduced due to the enhanced steric-hindrance of theelectron-withdrawing groups. Electronic absorption and emission properties of HL1, L2, 1 and 2 are alsoreported.Key Words : Palladium complexes, Electron-withdrwaing groups, Luminescence, Antibacterial activity, Cat-alytic activityIntroductionSchiff bases are important compounds due to their widerange of biological activities,
