Preparation, characterization, and circularly polarized luminescence of lanthanum and europium 1,1'-binaphthyl-2,2'-diyl phosphate complexes.

Solvated tris-complexes of (R)- and (S)-1,1'-binaphthyl-2,2'-dyil phosphate with lanthanum(III) and europium(III) centers were prepared and characterized by spectroscopic methods and elemental analysis. Circularly polarized luminescence (CPL) spectra for the optically active isomers of the europium complexes are also reported.
