Beschreibungen/Notizen

• Eu‐reka! Two neutral mononuclear europium enantiomers [Eu(tta)3L] and their thin films were prepared (tta=2‐thenoyltrifluoroacetonate; L=(−)‐4,5‐pinene bipyridine (1), L=(+)‐4,5‐pinene bipyridine (2)). The ferroelectric measurements of the thin films show E–P hysteresis loops at room temperature (Tc=28.0 °C) with remnant polarization of 0.022 μC cm−2 and a coercive field of 25 kV cm−1.
