文摘

The use of the rationally designed tridentate chelating ligand, 2,4,6,8-tetrakis(tert-butyl)-9-hydroxyphenoxazin-1-one containing the rigid tricyclic molecular framework with the ONO donor centers suitably arranged for the complexation with trivalent metal ions having sufficiently big ionic radii allowed preparation of new nonacoordinated Ln(III) complexes (Ln = La, Pr, Sm, Eu, Gd, Tb, Dy, Yb). The study of luminescent and redox properties of the prepared complexes, in particular their radical-anions the formation and stability of which is ensured by the redox-active hydroxyphenoxazinone ligands is currently underway.
