F64Pc2Ln (1Ln, Ln = Tb or Lu) represent the first halogenated phthalocyanine double-decker lanthanide complexes, and 1Tb exhibits single-molecule magnet properties as revealed by solid-state magnetometry. The fluorine substituents of the phthalocyanine rings have a dramatic effect on the redox properties of the F64Pc2Ln complexes, namely, a stabilization of their reduced states. Electrochemical and spectroelectrochemical measurements demonstrate that the 1Tb(-/2-) and 1Tb(2-/3-) couples exhibit redox reversibility and that the 1Tb(-), 1Tb(2-) and 1Tb(3-) species may be prepared by bulk electrolysis in acetone. Low-temperature MCD studies reveal for the first time magnetization hystereses for the super-reduced dianionic and trianionic states of Pc2Ln.
F64Pc2Ln（1Ln，Ln = Tb 或 Lu）代表第一个卤化酞菁双镧系金属配合物，1Tb 通过固态磁强计显示出单分子磁体性质。酞菁环上的氟取代基对 F64Pc2Ln 配合物的氧化还原性质有显著影响，即稳定其还原态。电化学和光谱电化学测量表明，1Tb(-/2-)和 1Tb(2-/3-) 对具有氧化还原可逆性，并且 1Tb(-)、1Tb(2-)和 1Tb(3-) 物种可以通过在丙酮中的批量电解来制备。低温 MCD 研究首次揭示了 Pc2Ln 的超还原二价和三价阴离子态的磁化滞后。
