Radical ligand-containing single-molecule magnets

Single-molecule magnetism of tetrapyrrole lanthanide compounds with sandwich multiple-decker structures

“…Schematic molecular structures of phthalocyanines used to construct SMMs. The 1,4,8,11,15,18,22,and 25 positions are referred as the α-sites and those at 2, 3,9,10,16,17,23, and 24 positions are the β-sites. M a n u s c r i p t 4 In the present review, we describe the historical evolution, magnetic properties, and magneto-structural relationships of diverse sandwich tetrapyrrole lanthanide-based SMMs, which are classified as: bis(phthalocyaninato), bis(porphyrinato), and mixed (phthalocyaninato)(porphyrinato) double-decker compounds;…”

The modular synthesis of rare earth-transition metal heterobimetallic complexes utilizing a redox-active ligand

“…4 It generated significant subsequent interest in multimetallic lanthanide radical bridged complexes. 5 The very recent reports of magnetic hysteresis at 60 K in a dysprosocenium cation are a testament to the power of the organometallic molecular design approach. 6,7 Our aim was to identify and use a redox-active bridging ligand with multiple and selective binding sites as the template for a general and modular synthetic route to heterometallic d-f or f-f′ complexes.…”

Field-Induced Slow Magnetic Relaxation of Mono- and Dinuclear Dysprosium(III) Complexes Coordinated by a Chloranilate with Different Resonance Forms

“…Molecule-based nanomagnets, such as single-molecule magnets (SMMs) [1][2][3][4][5][6][7] and single-ion magnets (SIMs) [8][9][10][11][12], are strictly low-dimensional magnetic systems that exhibit magnetization blocking at low temperatures, quantum tunneling of magnetization (QTM) [13], and quantum coherence [14,15]. Accordingly, SMMs have attracted a great deal of interest as promising candidates blocking at low temperatures, quantum tunneling of magnetization (QTM) [13], and quantum coherence [14,15].…”
