Antibacterial and aqueous dual-responsive sensing activities of monomeric complexes with uncoordinated imidazole sites

Abstract

Three monomeric complexes, [Co(HL)(HCOO)(H2O)]n (1) [Cd(HL)(H3CCOO)(H2O)]n (2) and [Ni(H2L)(H2O)2(NO3)2]n (3) (H2L = 6,6'-di(benzimidazo-2-yl)-2,2'-bipyridyl) have been solvothermal synthesized based on a well-designed semirigid benzimidazolyl ligand. The ligand chelating one metal ion constitutes the 0-D discrete butterfly-shaped monomer with uncoordinated imidazole sites. Antimicrobial activities showed that all compounds displayed effective inhibition of different bacteria. The three monomeric complexes are hydrolytically stable and slight soluble in water. Furthermore, the fluorescent monomeric complex 2 presents highly selective, sensitive detection of trace Cu2+ and Hg2+ in aqueous solution.
