Inside Cover: Sign Reversal of a Large Circularly Polarized Luminescence Signal by the Twisting Motion of a Bidentate Ligand (Chem. Eur. J. 28/2014).

The twisting motion of 3,3‐bis(diphenylphosphoryl)‐2,2‐bipyridine (BIPYPO) provides s‐cis and s‐trans geometries of a chiral EuIII complex containing tris[3‐(trifluoromethylhydroxymethylene)‐(+)‐camphorate], inducing the sign inversion of the negative circularly polarized luminescence (CPL) signals at the 5D0→7F1 transition of EuIII.
