Abstract
A series of new dimeric complexes with composition [Ln(2)(hfa)(6)(4-cpyNO)(3)](2:3 adduct, Ln=Sm-III-Dy-III, Tm-III) were synthesized and fully characterized. X-ray diffraction data of [Tb-2(hfa)(6)(4-cpyNO)(3)]center dot CHCl3 confirmed the dimeric structure; Tb ions are nine-coordinated by six O atoms from three hfa-ligands and three O atoms from three bridging 4-cpyNO molecules. The photophysical properties (absolute quantum yields and luminescence lifetimes) of the Eu-III and Tb-III 2:3 adducts are presented and compared with those of the 2:2 adducts. (C) 2007 Elsevier B.V.
