Synthesis, structure, and luminescent properties of lanthanide complexes containing 1,10-phenanthroline and perfluorinated 2-mercaptobenzothiazolate ligands

Mononuclear terbium and erbium complexes of the composition Ln(mbt^F)₃phen and the dinuclear complex Tb₂(mbt^F)₄(OH)₂(phen)₂ (mbt^F is 4,5,6,7-tetrafluoro-2-mercaptobenzothiazolate, phen is 1,10-phenanthroline) were synthesized. The structures of the complexes Er(mbt^F)₃phen and Tb₂(mbt^F)₄(OH)₂(phen)₂ were determined by X-ray diffraction. In the solid state, the terbium and erbium complexes exhibit intense metal-centered photoluminescence. Based on the complexes Ln(mbt^F)₃phen, double-layer organic light-emitting diodes (OLEDs) were assembled. These OLEDs exhibit electroplex emission with a band maximum at 630 nm.
