“…Besides, as shown in the paragraph devoted to the 2D CPs, the family of mpba ligands are very efficient FCUs that will lead to ferromagnetic coupling between the 2D layers that is needed to obtain MBMs. [88] [89] were obtained as bright green tiny crystals by slow diffusion of aqueous solutions of Na 4 As expected, the CPs adopts a 3D structure. However, the layers connected by the pillars do not adopt a honeycomb arrangement, but rather a semi-regular tiling of octagons and squares (4.8 2 -type network) (Figure 30a, b, d, and e).…”

Abstract:The aim of this review is to pay tribute to the legacy of O. Kahn. Kahn's credo was to synthesize magnetic compounds with predictable structure and magnetic properties. This is illustrated herein with results obtained by Kahn's group during his Orsay period thirty years ago, but also on the basis of our recent results on the synthesis of coordination polymers with oxamate ligands. The first part of this review is devoted to a short description of the necessary knowledge in physics and theoretical chemistry that Kahn and his group have used to select oxamate ligands, the complex-as-ligand strategy and the synthesis of heterobimetallic systems. Then, we describe the strategies we have later used to obtain the desired target compounds. The use of complexes as building-blocks, associated to a control of the metal ions chirality and stoichiometry, allowed us to obtain coordination polymers with predictable dimensionality. For the synthesis of single-chain magnets (SCMs) we show IncipitFor this thematic issue dedicated to the attractive legacy of Olivier Kahn, we decided to write this paper on magnetic coordination polymers built from polyoxalamide ligands. Some of the authors of this paper were part of the exciting adventure at the time of the creation of the Kahn's group at the University of Paris-Sud. Kahn's credo was to synthesize magnetic compounds with predictable structure and magnetic properties and in order to achieve this goal one needs some backgrounds in physics, theory and synthetic chemistry. We have therefore tried that the ligand chemical flexibility makes the isolation of the chains in the solid and the occurence of slow magnetic relaxation possible. For 1D and 2D molecule-based magnets (MBMs), the magnetic ordering strongly depends on the interchain or interplane interactions, which are difficult to control. Again the flexibility of the oxamate ligands allowed their strengthening in the solid sate, yielding MBMs with critical temperatures up to 30 K. We will also present our results on 3D coordination polymers, particularly on the porous magnets displaying large octagonal channels. This family of porous MBMs possess outstanding chemical properties, such as post-synthetic transformation in the solid state. Finally, we will also show that oxamate ligands allows the design of multifunctional materials, as in the case of the first chiral SCM. Overall, the results presented in this review show the impressive potential the oxamate ligands have for the design of coordination polymers.throughout this contribution to describe the historical process and the approach of the group's behind the choice of oxamate and oxamidate ligands to synthesize heterometallic coordination polymers.

“…48 In this approach, a metal complex with vacant additional coordination sites is first prepared and isolated, being used in a second step as a building block towards additional metal ions. 50 The structure consists of an extended parallel array of anionic, oxamato-bridged Mn 4 Cu 6 layers that are further interconnected through two m-phenylene spacers among the Cu II ions (Fig. 13).…”

Magnetic functionalities in MOFs: from the framework to the pore

2018

In this review, we show the different approaches developed so far to prepare metal-organic frameworks (MOFs) presenting electronic functionalities, with particular attention to magnetic properties. We will cover the chemical design of frameworks necessary for the incorporation of different magnetic phenomena, as well as the encapsulation of functional species in their pores leading to hybrid multifunctional MOFs combining an extended lattice with a molecular lattice.

“…47 It is noteworthy that similar or even higher CO 2 / CH 4 selectivity values have formerly been achieved by a variety of MOFs. 68,[71][72][73][74][75][76][77] In the previous theoretical study, 47 In order to determine the dynamic CO 2 /CH 4 adsorption selectivities of the UiO-66-X compounds, breakthrough experiments have been performed using equimolar mixtures of the two gases at 298 K. The methods for the breakthrough experiments and the corresponding curves (Fig. S16, ESI †) are presented in the ESI.…”

aThree new functionalized UiO-66-X (X = -SO 3 H, 1; -CO 2 H, 2; -I; 3) frameworks incorporating BDC-X (BDC: 1,4-benzenedicarboxylate) linkers have been synthesized by a solvothermal method using conventional electric heating. The as-synthesized (AS) as well as the thermally activated compounds were characterized by X-ray powder diffraction (XRPD), diffuse reflectance infrared Fourier transform (DRIFT) spectroscopy, thermogravimetric (TG), and elemental analysis. The occluded H 2 BDC-X molecules can be removed by exchange with polar solvent molecules followed by thermal treatment under vacuum leading to the empty-pore forms of the title compounds. Thermogravimetric analysis (TGA) and temperature-dependent XRPD (TDXRPD) experiments indicate that 1, 2 and 3 are stable up to 260, 340 and 360°C, respectively. The compounds maintain their structural integrity in water, acetic acid and 1 M HCl, as verified by XRPD analysis of the samples recovered after suspending them in the respective liquids. As confirmed by N 2 , CO 2 and CH 4 sorption analyses, all of the thermally activated compounds exhibit significant microporosity (S Langmuir : 769-842 m 2 g −1 ), which are comparable to that of the parent UiO-66 compound. Compared to the unfunctionalized UiO-66 compound, all the three functionalized solids possess higher ideal selectivity in adsorption of CO 2 over CH 4 at 33°C.
