Kondo, Mitsuru; Okubo, Takashi; Asami, Akiko; Noro, Shin-Ichiro; Yoshitomi, Tomomichi; Kitagawa, Susumu; Ishii, Tomohiko; Matsuzaka, Hiroyuki; Seki, Kenji published an article on January 15 ,1999. The article was titled 《Rational synthesis of stable channel-like cavities with methane gas adsorption properties: [{Cu2(pzdc)2(L)}n] (pzdc = pyrazine-2,3-dicarboxylate; L =a pillar ligand)》, and you may find the article in Angewandte Chemie, International Edition.Application of 64479-78-3 The information in the text is summarized as follows:
Porous coordination networks were designed in prepared copper complexes [{Cu2(pzdc)2(L)}n] (pzdc = pyrazine-2,3-dicarboxylate; L = pillar ligand pyrazine, 4,4′-bipyridyl, N-4-pyridinyl-4-pyridinecarboxamide). The structure of [{Cu2(pzdc)2(pyz)}.2H2O]n (1) was determined by x-ray crystallog. The complex consists of a pillared layer structure with a two-dimensional sheet of [Cu(pzdc)2]n and pillar pyrazine ligands that bridge each sheet. The channels are occupied by water mols. Thermal dehydration of 1 at 100-260° resulted in a stable phase which retained the porous network without decomposition (powder XRD study). Methane adsorption capabilities of the coordination networks were studied. Increased methane absorption activity for pillar ligands 4,4′-bipyridyl and N-4-pyridinyl-4-pyridinecarboxamide is consistent with the larger channel sizes of these complexes. The activity is comparable to that of zeolites and other reported stable porous coordination networks. The experimental process involved the reaction of N-(Pyridin-4-yl)isonicotinamide(cas: 64479-78-3Application of 64479-78-3)
N-(Pyridin-4-yl)isonicotinamide(cas: 64479-78-3) belongs to amides. Amides include many other important biological compounds, as well as many drugs like paracetamol, penicillin and LSD. Low-molecular-weight amides, such as dimethylformamide, are common solvents.Application of 64479-78-3
