The twisting motion of 3,3‐bis(diphenylphosphoryl)‐2,2‐bipyridine (BIPYPO) provides s ‐ cis and s ‐ trans geometries of a chiral Eu III complex containing tris[3‐(trifluoromethylhydroxymethylene)‐(+)‐camphorate], inducing the sign inversion of the negative circularly polarized luminescence (CPL) signals at the 5 D 0 → 7 F 1 transition of Eu III .
