Abstract

It has been demonstrated that copper-induced terbium(III) luminescence sensitization in heterometallic complexes with hydrazine-containing podands is caused by the ligand ring closure and joint coordination of both metal ions to the carbonyl oxygen atoms as well as, mainly, by the reduction with the hydrazine substituents of Cu(II) to Cu(I), which is able to sensitize terbium luminescence.
