One-dimensional Lanthanide Coordination Polymers Based on Butylene-2,2'-bis(oxybenzoic Acid), with Dy-compound Exhibiting White Light Emission

Five lanthanide-based coordination polymers: [Ln2(BBOA)3(H2O)]n (Ln = Sm (1), Eu (2), Gd (3), Tb (4), Dy (5), H2BBOA = butylene-2,2′-bis(oxybenzoic acid)) were synthesized and characterized. Ferromagnetic coupling exists between adjacent lanthanide ions in 4 and 5. Luminescence measurements show that compounds 1, 2, 4 and 5 all exhibit the characteristic transitions of corresponding lanthanide ions with compound 5 exhibits white emissions upon excitation.76
