Optimization in luminescent emission by extended quasi-planar and zigzag chainlike CuII-coordinated geometries

Multi-donor ligand H3IDC gives rise to different coordination geometries: quasi-plane and infinite zigzag chain by adjusting pH value in reaction systems with different alkaline substance. Photo-luminescent emission intensity and peak shape can be enhanced and narrowed by extended planar and octahedral CuII-coordinated geometries separately.
