Abstract
- Three dinuclear lanthanide complexes are achieved by using H<subscript>2</subscript>salen or H<subscript>2</subscript>salen/acac ligands (H<subscript>2</subscript>salen = N,N′-ethylenebis(salicylideneimine), acac = acetylacetonate). They are homodinuclear [Er<subscript>2</subscript>(salen)<subscript>3</subscript>] (1), [Yb<subscript>2</subscript>(salen)<subscript>2</subscript>(acac)<subscript>2</subscript>] (2), and heterodinuclear geometrical [ErYb(salen)<subscript>2</subscript>(acac)<subscript>2</subscript>] (3). The structures of complexes were determined by single crystal X-ray crystallographic studies and their photophysical properties were investigated. The homonuclear Yb<subscript>2</subscript> complex exhibits characteristic metal-centered NIR emission. The geometric ErYb isomer exhibits ‘dual emissions’ from both erbium(iii) and ytterbium(iii) ions. There was no detectable photoluminescence in the Er<subscript>2</subscript> complex, not only in solid state but also in solvent. [ABSTRACT FROM AUTHOR]
