“…In a pioneering work, carried out in UK and Spain, Douglas M. C. MacEwan (1917–2000) (Figure ) dedicated his initial efforts to study complexes of clay minerals with organic liquids . His later work at the Universities of Granada, Complutense de Madrid, and CSIC (Spain) extended this methodology to prepare other novel organic–inorganic hybrids by intercalation in related 2D solids, such as layered hydroxides and hydroxy salts as well as graphitic acids . This goal represented a key advance in the chemistry of hybrid compounds, as for instance, these last materials that were prepared by oxidation of graphite have been rediscovered within the graphene blooming, being nowadays known with the name of graphite oxide (GO).…”

The rise of organic-inorganic hybrid materials in both academia and industry results from a convergence of diverse expertise and communities and is driven by the curiosity of open-minded scientists. In this review article, a historical perception on the evolution of hybrid material science is described. The major periods associated with the genesis of hybrid materials are discussed: prebiotic hybrid chemistry, hybrid materials made through know-how, the rise of silicates and silicon chemistry, modern hybrids: a mushrooming multidisciplinary field of research, and current applications of hybrid materials fully integrated in the society. Finally, the review presents an outlook that summarizes some future prospects related to hybrid materials.

The catalytic activity of graphene oxide‐bound tetrakis(p‐aminophenyl)porphyrinatotin(IV) trifluoromethanesulfonate, [SnIV(TNH2PP)(OTf)2], in the trimethylsilylation of alcohols and phenols with hexamethyldisilazane (HMDS) is reported. The prepared catalyst was characterized using inductively coupled plasma analysis, scanning electron microscopy, transmission electron microscopy, and Fourier transform infrared and diffuse reflectance UV–visible spectroscopies. This heterogeneous catalyst was used for selective trimethylsilylation of various alcohols and phenols with HMDS in short reaction times and high yields. Also, the catalyst is of high reusability and stability, in that it was recovered several times without loss of its initial activity. The chemoselectivity of this catalytic system in the silylation of primary alcohols in the presence of secondary and tertiary alcohols and also phenols was investigated.

“…The hydrophilic nature of GO has already been reported in very early studies, 22 while by the 1960s it was already well known that GO swells in polar solvents with expansion of the interlayer distance from 6-7 Å to 40-50 Å depending on the molecular size and the amount of intercalated solvent. 23,24 Perhaps the most studied GO solvates by now are those with alcohols. Previous studies revealed that B-GO is intercalated with one layer of methanol, ethanol, and propanol under ambient conditions (in excess of solvent), while an increase in pressure or a decrease in temperature leads to reversible phase transition into a two-layered solvate phase.…”

Multilayered intercalation of 1-octanol into Brodie graphite oxide

et al. 2017

Multilayered intercalation of 1-octanol into the structure of Brodie graphite oxide (B-GO) was studied as a function of temperature and pressure. Reversible phase transition with the addition/removal of one layer of 1-octanol was found at 265 K by means of X-ray Diffraction (XRD) and Differential Scanning Calorimetry (DSC). The same transition was observed at ambient temperature upon a pressure increase above 0.6 GPa. This transition was interpreted as an incongruent melting of the low temperature/high pressure B-GO intercalated structure with five layers of 1-octanol parallel to GO sheets (L-solvate), resulting in the formation of a four-layered structure that is stable under ambient conditions (A-solvate). Vacuum heating allows the removal of 1-octanol from the A-solvate layer by layer, while distinct sets of (00l) reflections are observed for three-, two-, and one-layered solvate phases. Step by step removal of the 1-octanol layers results in changes of distance between graphene oxide planes by ∼4.5 Å. This experiment proved that both L- and A-solvates are structures with layers of 1-octanol parallel to GO planes. Unusual intercalation with up to five distinct layers of 1-octanol is remarkably different from the behaviour of small alcohol molecules (methanol and ethanol), which intercalate B-GO structure with only one layer under ambient conditions and a maximum of two layers at lower temperatures or higher pressures. The data presented in this study make it possible to rule out a change in the orientation of alcohol molecules from parallel to perpendicular to the GO planes, as suggested in the 1960s to explain larger expansion of the GO lattice due to swelling with larger alcohols.
