Thiazole and the Diazines Pyrazine and Pyrimidine as Sensitizers for Lanthanide Luminescence from VIS to NIR

Thiazole and the Diazines Pyrazine and Pyrimidine as Sensitizers for Lanthanide Luminescence from VIS to NIR
Sven H. Zottnick, Nicole Dannenbauer, Klaus Müller-Buschbaum
Complexes and coordination polymers were obtained from trivalent lanthanide chlorides together with thiazole (thz) and the diazine ligands pyrazine (pyz) and pyrimidine (pym). The compounds [Ln2Cl6(pyz)(thz)6]·2thz (Ln = Tb, Er), 1∞[Pr2Cl6(pyz)(thz)6], and [Ln2Cl6(pym)2(thz)4] (Ln = Tb, Er) could be obtained, their crystal structures, luminescence as well as thermal properties were determined. The compounds with Tb and Er show intense luminescence with a strong sensitizer effect of the ligands that can be observed by dominant ligand excitation and exclusive metal emission for VIS and NIR.
