Synthesis of supramolecular complexes based on tetracrown-substituted zinc porphyrinates was written by Mikhailitsyna, E. A.;Tyurin, V. S.;Beletskaya, I. P.. And the article was included in Protection of Metals and Physical Chemistry of Surfaces in 2010.Computed Properties of C10H21NO4 This article mentions the following:
New metal-porphyrin receptors functionalized by aza-crown-ether groups were synthesized. Main paths of supramol. self-assembly of porphyrin aza-crown-ether conjugates to bis-porphyrin sandwich complexes with metal and ammonium cations were studied using spectral methods of anal. (EAS, 1H, 13CNMR, MALDI-ToF mass spectrometry). Principal regularities of axial coordination of the obtained bis-porphyrin complexes with exobidentate ligands (1,4-diazabicyclo[2.2.2]octane and pyrazine) were studied. In the experiment, the researchers used many compounds, for example, 1,4,7,10-Tetraoxa-13-azacyclopentadecane (cas: 66943-05-3Computed Properties of C10H21NO4).
1,4,7,10-Tetraoxa-13-azacyclopentadecane (cas: 66943-05-3) belongs to ethers. The oxygen atom in ethers are more electronegative than carbon, thus the hydrogens which are alpha to the ethers are more acidic than the simple hydrocarbons. Ethers can form hydrogen bonds with other molecules (alcohols, amines, etc.) that have O閳ユ椊 or N閳ユ椊 bonds. The ability to form hydrogen bonds with other compounds makes ethers particularly good solvents for a wide variety of organic compounds and a surprisingly large number of inorganic compounds.Computed Properties of C10H21NO4
