A diterbium(III) complex was synthesized by using p-tert- butylsulfonylcalixarene, 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 TbIII 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.
