“…The group of Barbiou has recently developed a number of adaptive membranes for the transport of gas or ions using dynamic constitutional systems and supramolecular chemistry. 481,[486][487][488][489][490] For example, they have reported one of the rare examples of a water and proton transporter 491 using ureidoimidazole quartets that form barreled channels in a membrane environment, the system being inert for transporting Li + and Na + . 487 MOFs.…”

In this review, we survey the diversity of structures and functions which are encountered in advanced self-assembled nanomaterials. We highlight their flourishing implementations in three active domains of applications: biomedical sciences, information technologies, and environmental sciences. Our main objective is to provide the reader with a concise and straightforward entry to this broad field by selecting the most recent and important research articles, supported by some more comprehensive reviews to introduce each topic. Overall, this compilation illustrates how, based on the rules of supramolecular chemistry, the bottom-up approach to design functional objects at the nanoscale is currently producing highly sophisticated materials oriented towards a growing number of applications with high societal impact.

“…This is particularly clear in the field of multifunctional hybrid materials. Indeed, today we are witnessing an increasing activity in the controlled synthesis of hybrid materials, [1,[8][9][10][11] combining concepts from several disciplines to obtain new materials with specific chemical, [12][13][14][15][16][17][18][19][20] physical [12,13,16,21,22] or biological properties.

The hybridization of simple transition metal hydroxides provides prototypical examples of layered magnetic and bifunctional hybrid materials in which the influence of the hybrid interface on the behavior of multiproperty systems can be evaluated. AbstractThis article is a critical review on layered hybrid organic-inorganic functional structures. We specially discuss series of results concerning the design of magnetic and multiproperty systems derived from hybridization of layered transition metal hydroxides. Series of hybrid materials showing original magnetic properties are reviewed, which were prepared by functionalization of layered simple hydroxides (LSH) of general formula M 2 (OH) 3 A (M = Co, Cu, Ni, Zn, ... and A = NO 3 -, OAc -, alkylcarboxylates, peptides, metal complexes...). To make the point on this vast family of hybrid compounds, we present first the work investigating the mechanism of interaction and the structural factors influencing the magnetic properties of hybrid materials based on LSH. Then we detail how even more complex anions can be immobilized and grafted into the interlamellar space giving rise to new functionalities. These systems are very good models for understanding the correlations between the structure of hybrid systems and the physical properties brought by the inorganic host and by the molecular moieties grafted onto the inorganic metal network. The interface between the organic and inorganic components, i.e. chemical bonding, charge density, or local pressure, is essential for the control of the properties of multifunctional hybrid systems. Some conclusions are drawn on the future of this approach, useful for developing new two-dimensional functional systems.

“…For all these reasons, in this study, nanometric macromonomers and dialdehyde core connectors have been used to conceive dense ROFs for the preparation of dynameric membranes for selective gas transport. [22][23][24][25] The isophthalaldehyde (1), the bis(3-aminopropyl)-polytetrahydrofuran (Mn~1100 g mol Compounds (Figure 2 a) generate dynameric membranes based on three structural features: 1) The hydrophobic linear polyTHF (1) has been used to generate rigid crystalline phases considered to have low-permeability for gas transport.…”

Among the industrial methods used for capturing CO 2 (absorption, distillation, etc.), [1] membrane technology, [2][3][4][5][6][7][8][9][10][11] which offers advantages such energy saving, simple design and scale-up, is becoming continually more prevalent. High permeability combined with reasonable selectivity is the most important goal in developing membranes for gas separation. This goal is usually achieved through the use of polymeric membranes, through which gas transport is controlled by gas-diffusivity in glassy polymers and by gas-solubility in rubbery polymers. De novo design of synthetic membrane materials like blockco-polymers, [2][3][4][5] polymeric composites, [6,7] mixed-matrix hybrids [8] and pseudo-microporous polymers [9][10] metal organic frameworks-MOFs [1,11] has been identified as an emerging area of interest. The combination or replacement of classical glassy polymers with crystalline MOFs, ZIFs, or zeolites provides molecularly controlled permeability and selectivity. However, attempts to obtain mechanically stable and homogeneous layers on various supports have been met with difficulty.Taking advantage of the high permeabilities and flexible casting properties observed for rubbery polymers, we decided to build ROFs as new membrane separation systems for gases. ROFs may provide premises for more fine structural interaction of diffusing gas molecules with molecular addressable domains. Minimizing the size of ultradense addressable transporting domains [12][13][14][15] would make it possible to improve the limits of interaction of gas molecules with percolated conductive domains with high diffusional behaviors. [16][17][18][19] Such an improvement is specifically of interest to membrane scientists (Figure 1).Furthermore, the size of addressable elementary domains for the diffusion of gas molecules is reminiscent of the situation where pixel size determines the quality of resulting images in LCD devices. Within this context, we previously showed that dynamic covalent polymers, [15] or dynamers, [20][21][22][23] generated from reversibly interacting monomers, offer the possibility to address these issues. [24,25] In dynamers, the components are reversibly connected, and they self-assemble in such a fashion that their overall morphology overrides defects during the forAbstract: Obtaining high permeability whilst keeping a reasonable selectivity is the most important challenge in the development of membrane systems for gas separation. Satisfactory performance is usually obtained with polymeric membranes through which gas transport is controlled by gas-diffusivity in glassy polymers and by gas-solubility in rubbery polymers. During the last decade, important advances in this field have been made possible by molecular control of gas separation properties.
