Construction of a crystalline 14-metal Zn–Nd rectangular nanocluster with a dual-emissive response towards metal ions

Abstract

A crystalline 14-metal Zn–Nd nanocluster was constructed, and it shows ligand-centered and lanthanide fluorescence response towards metal ions.

Recent Advances of Near-Infrared (NIR) Emissive Metal Complexes Bridged by Ligands with N- and/or O-Donor Sites

“…In recent years, with the development of NIR luminescence materials, salicylaldehyde Schiff base derivatives with long alkyl chains have been widely used as bridged ligands in the synthesis of NIR complexes with bridging ligands [47][48][49][50][51]. These flexible ligands can exhibit various coordination modes with metal ions and have interesting structures and properties.…”

A High-Symmetry Double-Shell Gd30Co12 Cluster Exhibiting a Large Magnetocaloric Effect

“…The cluster core of [Gd 30 Co 12 (OH) 56 (NO 3 ) 12 ] 52+ consists of six dicubane-like [Gd 5 Co 2 (μ 3 -OH) 8 ] 12+ units formed through two adjacent cubane-like [Gd 3 Co­(μ 3 -OH) 4 ] 7.5+ units sharing one Gd III vertex (Figure a). Each dicubane-like [Gd 5 Co 2 (μ 3 -OH) 8 ] 12+ unit connecting with four adjacent neighbors respectively through four NO 3 – anions in a μ 5 -η 2 :η 2 :η 3 mode observed in Ln 8 Zn 6 (Figure S4) and three neighbors through one μ 3 -OH – bridge forms a cluster core of [Gd 30 Co 12 (OH) 56 (NO 3 ) 12 ] 52+ (Figure b). Gd1 is coordinated by nine oxygen atoms with six from four μ 3 -OH – , two from two NO 3 – anions, and one from one acetate in a spherical tricapped trigonal-prismatic configuration calculated by continuous-shape measurements (CShM; Table S2).…”
