摘要

The pentagonal bipyramidal single-ion magnets (SIMs) are among the most attractive prototypes of high-performance single-molecule magnets (SMMs). Here, a fluorescence- active phosphine oxide ligand CyPh_2PO (=cyclohexyl- (diphenyl)phosphine oxide) was introduced into [Dy- (CyPh_2PO)_2(H_2O)_5]Br_3·2 (CyPh_2PO)·EtOH·3H_2O, and combined dynamic magnetic measurement, optical characterization, ab initio calculation, and magneto-optical correlation of this high-performance pseudo-D_(5h) Dy~(III) SIM with large Ueff (508(2) K) and high magnetic hysteresis temperature (19 K) were performed. This work provides a deeper insight into the rational design of promising molecular magnets.
