O (Ln = Ho (

1–3
are isostructural and show a dinuclear motif, which further develop into a 3D H-bonding supra-molecular structure, and compounds
4
–
6
are also isostructural and have a 1D ladder-typed chain, which further interlinked into a 3D supra-molecular architecture by H-bonding interactions. Furthermore, the fluorescent properties of compounds
3
–
6
exhibit intense emissions corresponding to blue-violet (
3
and
4
), red (
5
) and orange red (
6
), respectively. By way of the careful regulation of the relative intensity of the blue-violet (
4
), green (Tb) and orange red (
6
) emissions, a novel three-component white-light emission (Ho–Sm–Tb) has been realized. |
