Complexes of Eu(iii)(hfa)3 with a planar chiral P(iii) ligand (Phanephos): solvent-sensitive sign inversion of circularly polarised luminescence

Abstract

Complexes of Eu(III)(hfa)₃ with a C₂-symmetric planar P(III) ligand exhibited intense circularly polarised luminescence (CPL) due to ⁵D₀ → ⁷F₁ and ⁵D₀ → ⁷F₂ transitions, with the signs and shapes of CPL signals depending on the choice of solvent (acetone or chloroform).
