Abstract

Twou nique heterometallic cluster organic frameworks, [Cd 4 Mn III 4 Mn II 6 (Tri) 4 (CH 3 COO) 14 (m 4 -O) 2 (m 3 -O) 2 (H 2 O) 2 ] Cd(H 2 O) 2 ·9 H 2 O( 1)a nd Cu[Cd 5 Cu 6 (Tri) 4 (CH 3 COO) 9 (H 2, have been successfully prepared by employing ab ifunctionalt ripodala lcohol ligand as as tructure-directing agent. Crystal structure analyses revealt hat 1 represents ar are example of frameworks constructed from CdÀMn heterometallic chains, and 2 is the first heterometallic MOF based on highest-nuclear CdÀCu heterometallic cluster buildingb locks. Furthermore, the magnetic properties and gas adsorption abilities of 1 and 2 were systematically studied.

Structure and assembly mechanism of a centipede-shaped high-nuclear Dy14Cu12heterometallic nanocluster

“…The common method is to assemble metal ions into the anticipated structures using well-designed organic ligands with a special geometry and size and multiple coordination groups which contribute a significant role in the construction of high-nuclear heterometallic clusters. 8–10 In the past decades, some well-designed hydroxyl- or carboxylato-containing ligands were employed to build high-nuclear 4f and 3d–4f clusters, such as Gd 104 , 11 Ln 60 , 12 Dy 72 , 13 La 20 Ni 30 , 14 Gd 40 Ni 44 , 15 Ni 36 Gd 102 , 16 Cu 24 Ln 6 , 17 Cu 9 Dy 2 , 18 Gd 30 Co 12 , 19 Cu 36 Ln 24 , 20 Mn 8 Ln 8 , 21 Ln 24 Zn 4 , 22 Fe 10 Ln 10 , 23 and Fe 16 Ln 4. 24 Most of them are homometallic lanthanide clusters, and heterometallic Ln–M clusters (M = Co, Ni, Mn).…”

Lanthanide-Anderson Polyoxometalates Frameworks: Efficient Sulfide Photooxidation

“…Dipyridyl-Anderson POMs are linear linkers with high symmetry. Herein, the POM ligand [N( n -C 4 H 9 ) 4 ] 3 [MnMo 6 O 18 (TRI) 2 ] (L) was synthesized from a one pot reaction of 2-(hydroxymethyl)-2-(pyridin-4-yl)-1,3-propanediol (H 3 TRI), − (TBA) 4 [α-Mo 8 O 26 ], and Mn(CH 3 COO) 3 ·2H 2 O. The combination of L, dicarboxylate linker, and Ln ions produced three POM-MOFs [Tb 2 L(BPDC) 1.5 (DMF) 6 ] n ( Tb-1 ), [Eu 2 L(BPDC) 1.5 (DMF) 6 ] n ( Eu-1 ), and [Tb 2 L(2,6-NDC) 2 (DMF) 4 ] n ( Tb-2 ) (H 2 BPDC = 4,4-biphenyldicarboxylic acid; 2,6-H 2 NDC = 2,6-naphthalenedicarboxylic acid; DMF = N , N -dimethylformamide).…”

Reversible Structural Transformation of CuI–TbIII Heterometallic MOFs with Highly Efficient Detection Capability toward Penicillin

“…By virtue of these outstanding features, aptamers can be used to build aptasensors to monitor analytes. , Significantly, electrochemical biosensors are of concern in food safety and environmental monitoring for the reasons of low operation cost, available portability, remarkable sensitivity, and exceptional selectivity. , In addition, diversified materials have been developed to amplify detection signals. − Metal–organic frameworks (MOFs) have been designed and used in many applications, − but their instability directly restricts the actual use of MOFs. Notably, heterometallic MOFs have attracted increasing interest in recent years, because such MOFs have plentiful structures, high stability, and fine photoelectric properties. − As we know, only a few reported MOFs have been developed to prepare aptasensors for electrochemical detection. − However, no heterometallic MOFs have been reported as electrochemical aptasensors to monitor penicillin.…”
