摘要
A series of chiral two-dimensional lanthanide coordination polymers, [Ln2（L）3（H2O）6]n·n/3H2O[Ln=Nd （la, lb）, Sm （2）, Eu （3）, Tb （4）, Dy （5）, Ho （6）, Er （7）; H2L=2,2-dihydroxylmalonic acid], have been hydrothermally synthesized by using dihydroxyfumaric acid as a source of polydentate O-donor ligands. The luminescence behav- iors of 3 and 4 have been investigated, and they exhibit strong red and green fluorescence in the visible region respectively.
