Abstract
- Single-molecule magnets (SMMs) are regarded as promising candidates for ultrahigh-density storage, quantum information processing and molecular spintronics. It is a crucial challenge for chemists to modulate magnetic dynamics of SMMs. Here, we successfully synthesized two 3d-4f polynuclear compounds [Co<subscript>2</subscript>Dy(TTTT<superscript>Cl</superscript>)<subscript>2</subscript>(MeOH)]NO<subscript>3</subscript>·3MeOH (1) and [Co<subscript>2</subscript>Dy(TTTT<superscript>Cl</superscript>)<subscript>2</subscript> (MeOH)][Co(HTTTT<superscript>Cl</superscript>)](NO<subscript>3</subscript>)<subscript>2</subscript>·2.5MeOH·2H<subscript>2</subscript>O (2), where H<subscript>3</subscript>TTTT<superscript>Cl</superscript>=2,2′,2′′-(((nitrilotris(ethane-2,1-diyl)) tris(azanediyl)) tris(methylene))tris-(4-chlorophenol). On applying the approach by co-crystallization of bulky diamagnetic moiety, the effective energy barrier enhances from 401 K (1) to 536 K (2), which are both among the highest d-f heterometallic SMMs. [ABSTRACT FROM AUTHOR]
