Complexes of Sc, La, Sm, Gd, Tb and Yb with 1,3-di-tert-butyl-7methylacridin-4-olate (Acr Me ) and 1,3-di-tert-butyl-7-bromoacridin-4-olate (Acr Br ) ligands were obtained by reactions of respective acridinols with cyclopentadienides or tris (trimethylsilyl)amides of rare earth metals or by metathesis of metal chlorides with Na(Acr R ). The Sc and La complexes with Acr Me ligands revealed photo-and electroluminescence of moderate intensity while the Sm, Gd, and Tb complexes, as well as all complexes with Akr Br ligands, turned out to be luminescent inactive. The La(Akr Br ) 3 and Yb(Acr Br ) 3 complexes showed photovoltaic properties. The best results of energy conversion were achieved on three-layer model devices containing a lanthanum complex as a photoactive material.
