Lanthanide coordination polymers for multi-color luminescence and sensing of Fe3 +

• Multi-color and close white color luminescence are tuned for [H2Me2]3[Ln(DPA)3].
• [H2NMe2]3[Tb(DPA)3] performs selective and sensitive luminescence sensor for Fe3 +.

Luminescent lanthanide coordination polymers [H2NMe2]3[Ln(DPA)3] (Ln = Eu, Tb, Sm, Dy; [H2NMe2]+ = dimethyl amino cation; H2DPA = 2,6-dipicolinic acid) are synthesized, whose multi-color can be tuned and even white color luminescence can be integrated. Besides, the fluorescent sensing property of the [H2NMe2]3[Tb(DPA)3] system is checked, which shows selective fluorescent quenching effect for Fe3 +.
