In an article, author is Dong, Jun-Liang, once mentioned the application of 4949-44-4, Name is Ethyl 3-oxopentanoate, molecular formula is C7H12O3, molecular weight is 144.17, MDL number is MFCD00009317, category is pyridazines. Now introduce a scientific discovery about this category, Quality Control of Ethyl 3-oxopentanoate.
Cobalt MOTs base on benzimidazoi and varied carboxylate ligands with higher capacitance for supercapacitors and magnetic properties
Five new three-dimensional (3D) cobalt-based metal-organic frameworks (MOFs), [Co(L)(0.5)(1,4-BDC)](n), (1), [Co-3(L)(1,2,4-TBC)(2)(H2O)(4)](n) (2), [Co-1.5(L)(1,2,4,5-FIBTC)(H2O)(2)](n) (3), [Co(L)(5-AIPC)(n) (4), and [Co(L)(1,4NDC)](n) (5), (L = 3,6-bis(benzimidazol-1-yl)Pyridazine; 1,4-H2BDC = terephthalic acid; 1,2,4-H3BTC = benzene-1,2,4-tricarboxylic acid; 1,2,4,5-H4BTC = benzene-1,2,4,5-tetracarboxylic acid; 5-H(2)AIPC = aminoisophthalic acid; 1,4-H2NDC = naphthalene-1,4-dicarboxylic acid) have been synthesized, and then characterized by IR spectroscopy, thermogravimetric analysis, elemental analysis, powder X-ray diffraction, and single-crystal X-ray diffraction. The structure analysis displays that complexes 1-5 have a 3D network, which 1 displays a 2-fold interpenetrating 3D framework structure with the point symbol of (4(12).6(3)), 2 have a 8-connected 3D framework structure with the point symbol of (3(6).4(14) 5(7).6) and 3 displays a 2,6-connected 3D new topological structure with the point symbol of (4(4).6(10).10)(6). Co-MOFs were evaluated as an electrode material for supercapacitors. Complex 1 displayed a higher specific capacitance of 281 F g(-1) in 6 M KOH solution at a current density of 1 A g(-1) and remained at 195 Fri after 2000 cycles at 2 A g(-1). In addition, the magnetic properties of complexes 1-5 have been investigated and discussed.
