Abstract

Mononuclear terbium and erbium complexes of the composition Ln(mbtF)3phen and the dinuclear complex Tb2(mbtF)4(OH)2(phen)2 (mbtF is 4,5,6,7-tetrafluoro-2-mercaptobenzothiazolate, phen is 1,10-phenanthroline) were synthesized. The structures of the complexes Er(mbtF)3phen and Tb2(mbtF)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(mbtF)3phen, double-layer organic light-emitting diodes (OLEDs) were assembled. These OLEDs exhibit electroplex emission with a band maximum at 630 nm.
