Alkali metal-linked triangular building blocks assemble a high-nucleation lanthanoid cluster based on single-molecule magnets

Different anion (NO3− and OAc−)-controlled construction of dysprosium clusters with different shapes

“…The results indicate that their Dy( iii ) ions might have low excited states and/or magnetic anisotropy. 64,65 In addition, when the temperature and magnetic field reached 2 K and 7 T, respectively, the maximum values of 4 and 5 were 61.6 and 63.53 Nβ , respectively (Fig. S8†).…”

“…This decreasing χ m T value with temperature may be caused by the gradually decreasing Stark level of the excited state of the thermally reduced Dy(III) ion and/or the crystal field effect. 63,64 Furthermore, there is a weak increase in the χ m T of cluster 4 in the high temperature region. As the temperature decreases, the maximum value of 36.23 is reached at 89 K. Finally, it exhibits a decreasing trend in the low temperature area and reaches a minimum value of 23.9 cm 3 K mol −1 at 2 K. In summary, cluster 4 exhibits weak antiferromagnetic interactions.…”

Enhancement of Luminescence, Multiple-Sensing, and Differentiated Live-Cell-Imaging Properties of High-Nuclear Lanthanide Nanoclusters via the Zn(II)-Chelate-Controlled Dual Antenna Effect

“…[8][9][10] The hysteresis loops of Dy 9 Zn 8 and Tb 9 Zn 8 were not obvious at 2 K (Figure S16), which is possibly due to strong quantum tunneling and crystal field effects. 11 The slow relaxation behavior and temperature dependence of Dy 9 Zn 8 were further explored.
