“…10) By using this difference in reactivity, the preparation of two types of intercalation compounds, A-type intercalation compounds where guest species are present in every other interlayer and Btype intercalation compounds whose interlayers are completely occupied by guest species, has been achieved. 56) It is possible to prepare two types of oraganophosphonate derivatives by using these two types of intercalation compounds as intermediates.…”

Recent developments in the preparation of inorganic and inorganic organic hybrid materials from inorganic layered compounds are reviewed. The focus is placed on three topics: preparation of new ion-exchangeable layered perovskites and a tungstic acid from Aurivillius phases via selective leaching of bismuth oxide sheets; grafting reactions for the preparation of two-dimensional inorganic organic hybrids; and conversion of two-dimensional inorganic organic hybrids into inorganic compounds.

“…[2][3][4] Due to the large diversity of existent layered compounds, from which 2D nanomaterials are derived, an almost infinite variety of 2D layered compounds can be produced. 5 Various families of layered compounds have been identified, and they include boron nitride, transition metal di-and tri-chalcogenides, 6,7 layered metal oxides, 8,9 metal halides, transition metal carbides 10 and nitrides, and layered double hydroxides. 8 Inorganic 2D nanomaterials are highly attractive because they exhibit unusual properties absent in their bulk counterparts.…”

“…2 Further interest on 2D nanomaterials resides in the possibility to combine them in rationally designed functional materials with enhanced properties for various applications includ ing photocatalysis, biosensing, devices using superparamagentic films and devices generating photocurrent and photoluminiscence. 2,9 2D nanomaterials have been used as building blocks of hierarchically organized nanostructures manufactured by various methods: layer-by-layer deposition (multilayers, superlattices), 12 ' 13 Langmuir-Blodgett deposition (multilayers, su-perlatttices), 12 ' 13 flocculation (ions interstratified with 2D nanomaterials). 14-16 Moreover, the multilayers can then be further engineered 8,9,12 for instance introducing pores using tem-plating techniques 17 or freeze-drying 18 and forming microspheres by spray-drying.…”

E -m a i l : b e a t r i x . m e n d o z a @ g m a i l . c o m"These authors contributed equally to this work Abstract Manganese oxide nanosheets were synthesized using liquid-phase exfoliation that achieved suspensions in isopropanol with concentrations of up to 0.45 mg ml -1 . A study of solubility parameters showed that the exfoliation was optimum in N,N-Dimethylformamide followed by isopropanol and diethylene glycol. Isopropanol was the solvent of choice due to its environmentally friendly nature and ease of use for further processing. For the first time, a hybrid of graphene and manganese oxide nanosheets was synthesized using a single-step co-exfoliation process. The 2D hybrid was synthesized in isopropanol suspensions with concentrations of up to 0.5 mg ml -1 and demonstrated stability against re-aggregation for up to 6 months. The co-exfoliation was found to be a energetically favorable process in which both solutes, graphene and manganese oxide nanosheets, exfoliate with an improved yield as compared to the single-solute exfoliation procedure. This work demonstrates the remarkable versatility of liquid-phase exfoliation *To whom correspondence should be addressed 2 with respect to the synthesis of hybrids with tailored properties, and it provides proof-of-concept ground work for further future investigation and exploitation of hybrids made of two or more 2D nanomaterials that have key complementary properties for various technological applications.

“What would the properties of materials be if we could really arrange the atoms (molecules) the way we want them?” Besides, Feynman conjectured “What could we do with layered structures with just the right layers?” The chemistry of layered zirconium phosphate (ZrP) gives excellent possibilities to achieve the goal of designing porous solids of controlled molecular geometry, a challenge of enormous technological and scientific importance. The placing of organic molecules between the layers of ZrP is quite straightforward, can easily be controlled, and leads to enduring solid materials where the confinement makes the organic molecules to show new properties at the supramolecular level. The chemistry of metal phosphates/phosphonates will be detailed in relation with the following topics: (i) molecular recognition; (ii) chemically driven porosity changes; (iii) chiral memory and supramolecular chirality; (iv) luminescence signaling; (v) photoinduced electron‐transfer processes; (vi) hydrogen storage; and (vii) confinement of drugs.
