A diterbium(III) complex was synthesized by using p‐tert ‐butylsulfonylcalix[4]arene, which adopts a 1,2‐alternate conformation, acts as a sensitive optical‐antenna chromophore for UV and near‐UV light and causes easy‐axis magnetic anisotropy in the Tb III ions. The complex showed efficient ff emission with a corrected quantum yield of ca. 85 % even at room temperature. In addition, it showed superparamagnetic behaviour due to slow magnetic relaxation at low temperatures.(© Wiley‐VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2008)
