Luminescent single-molecule magnet of metallofullerene DyErScN@Ih-C80
metallofullerene, single-molecule magnet, near-infrared photoluminescence
Magneto-luminescent molecules have significant applications in data storage and quantum computing. However, design of these bi-functional molecules coupled with magnetic behavior and photoluminescence is still challenging. In this work, we report a metallofullerene DyErScN@Ih-C80 exhibiting single-molecule magnet (SMM) behavior and near-infrared emission. For DyErScN@Ih-C80, two functional lanthanide metal ions of Dy3+ (SMM function) and Er3+ (luminescent function) are integrated inside a fullerene cage using a trimetallic nitride template, and its structure has been unambiguously characterized by single-crystal X-ray diffraction. Magnetic measurements revealed that DyErScN@Ih-C80 behaves as a SMM with a blocking temperature up to 9 K resulting from the intramolecular magnetic interaction between Dy3+ and Er3+ ions. Moreover, DyErScN@Ih-C80 exhibits temperature-dependent near-infrared emission around 1.5 µm with multiple splitting peaks from Er3+, which arises from the influence of Dy3+ ion. This study provides a new strategy to synthesize new magneto-luminescent molecule materials.
