| Popis: | A series of 12 lanthanide coordination polymers was synthesized from anhydrous LnCl3 and 1,2-di(4-pyridyl)ethylene (dpe) under solvothermal conditions in either thiazole (thz) or pyridine (py). The reactions yielded ∞1[Ln2Cl6(dpe)2(thz)4]·dpe with Ln = Ce (1), Nd (2), ∞1[LnCl3 (dpe)(py)2]·(dpe/py) with Ln = Gd (3), Er (4), and ∞1[LnCl3(dpe) (thz)2](dpe/thz) with Ln = Sm (5), Gd (6), Tb (7), Dy (8), Er (9), Yb (10), as well as ∞1[HoCl3(dpe)(thz)2]·thz (11) and ∞2[La2Cl6(dpe)3(py)2]·dpe (12). One-dimensional coordination polymers (CPs) and a two-dimensional network of five different constitutions are formed by connection of LnCl3 units via dpe molecules. As free ligand, dpe shows an excimer effect that is reduced in the coordination polymers. In addition, dipyridylethylene proves to be a suitable sensitizer for the photoluminescence of lanthanides in the near-infrared region (NIR) only. Thereby, dpe differs from the related ligand 1,2-di(4-pyridyl)ethane. For the compounds presented, four different luminesc... |
