Abstract
Two new ZnII complexes of 2-(2-hydroxyphenyl)benzimidazole (Hpbm), and 5-amino-2-(1H-benzoimidazol-2-yl)phenol (Hapbm), namely [Zn(pbm)2] (1), and [Zn(apbm)2]·C2H5OH·H2O (2), as well as the ligands themselves, have been prepared and characterized by X-ray crystallography and photoluminescence studies. Both 1 and 2 are neutral, mononuclear molecules that display strong photoluminescence in the blue regionand thus may serve as candidates for blue-light-emitting electroluminescent materials. The electronic transitions in the photoluminescent processes have also been investigated by means of time-dependent density functional theory (TDDFT) energy level and molecular orbitals analyses, which show that their absorption and luminescent properties are ligand-based.
