Novel triarylazoimidazoles and their group 12 metal complexes, containing strong electron donors or acceptors, were synthesized and characterized. The complexes exhibited red photo-luminescence emission in solution, and showed antibacterial activity against Gram-positive microorganism S. aureus and Gram-negative microorganism E. coli.
Novel triarylazoimidazoles containing strong electron donors (p-NEt2) or acceptors (p-NO2) by the azoaryl group, and their group 12 metal complexes were synthesized and fully characterized, including X-ray analysis for several complexes. Novel complexes exhibit red photo-luminescence emission (phi up to 0.21) in a solution. Moreover, the antibacterial activity of complexes was tested against Gram-positive microorganism S. aureus and Gram-negative microorganism E. coli.
