“…These results suggest the formation of C = N and aliphatic C−H bonds in the obtained P-SWN, probably caused by the deamination of the aminal linkages 21 and the partial hydrogenation by Li-EDA. In brief, the aromatic rings in the SWN will be partially hydrogenated by Li-EDA, which is widely used for the hydrogenation of aromatic rings (Benkeser reaction) 22 23 24 . It should be noted that SWN was synthesized through the reaction of primary amines and the imine bonds in Schiff-base.…”

Porous organic frameworks (POFs) based membranes have potential applications in molecular filtration, despite the lack of a corresponding study. This study reports an interesting strategy to get processable POFs dispersion and a novel ultrathin sandwich-like membrane design. It was accidentally found that the hydrophobic N-rich Schiff based POFs agglomerates could react with lithium-ethylamine and formed stable dispersion in water. By successively filtrating the obtained POFs dispersion and graphene oxide (GO), we successfully prepared ultrathin sandwich-like hybrid membranes with layered structure, which showed significantly improved separation efficiency in molecular filtration of organic dyes. This study may provide a universal way to the preparation of processable POFs and their hybrid membranes with GO.

SUMMARY Recently, graphene has received great attention as potential hydrogen storage media. Here, we report a new route to store/chemisorb high content of hydrogen on graphene by employing Benkeser reaction. Graphene nanosheets are produced via a soft chemistry synthetic route involving oxidation of graphite using Improved method, ultrasonic exfoliation, and chemical reduction by using hydrazine with overnight heat treatment. Graphene is hydrogenated by using lithium in ethylenediamine under Benkeser reaction at atmospheric pressure and 30 °C. Benkeser reaction overcomes the liquid ammonia handling and produced multiple layer of graphene attached to the hydrogen atoms. High‐resolution transmission electron microscopy and selected area electron diffraction analysis confirm the ordered graphite crystal structure of graphene and reveal the rough, corrugated hydrogenated graphene layers attached by hydrogen atoms. Fourier transformation infrared spectroscopy analysis confirms that hydrogen adsorption occurs at all the ortho, meta, and para positions of aromatic graphene. The degree of hydrogenation of graphene estimated by thermogravimetric analysis reveals 14.67% (weight %) hydrogen storage, which is considerably higher than the earlier reported values of percentage storage achieved using various physisorption and chemisorption techniques.

Reduction of benzene and tetrahydronaphthalene (tetralin) was achieved by electrolysis in ethylenediamine saturated with lithium chloride. This reduction could also be carried out with tetrabutylammonium iodide as the supporting electrolyte. In the absence of a substrate, electrolysis of a solution of lithium chloride in ethylenediamine produced the blue color of the solvated metal.) unless CC License in place (see abstract).
