A molecular gate based on a porphyrin and a silver lock was written by Guenet, Aurelie;Graf, Ernest;Kyritsakas, Nathalie;Allouche, Lionel;Hosseini, Mir Wais. And the article was included in Chemical Communications (Cambridge, United Kingdom) in 2007.Safety of 2-(2-(2-((Tetrahydro-2H-pyran-2-yl)oxy)ethoxy)ethoxy)ethan-1-ol This article mentions the following:
A Sn(IV) metallaporphyrin, bearing a 4-pyridyl group on one meso position and a handle equipped also with a pyridyl unit, functions in solution as a mol. gate in the presence of Ag cation. The complexation-decomplexation of Ag(I) corresponds to the opening and closing motions of the gate. The crystal structure of the Sn metallaporphyrin was determined In the experiment, the researchers used many compounds, for example, 2-(2-(2-((Tetrahydro-2H-pyran-2-yl)oxy)ethoxy)ethoxy)ethan-1-ol (cas: 60221-37-6Safety of 2-(2-(2-((Tetrahydro-2H-pyran-2-yl)oxy)ethoxy)ethoxy)ethan-1-ol).
2-(2-(2-((Tetrahydro-2H-pyran-2-yl)oxy)ethoxy)ethoxy)ethan-1-ol (cas: 60221-37-6) 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―H or N―H 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.Safety of 2-(2-(2-((Tetrahydro-2H-pyran-2-yl)oxy)ethoxy)ethoxy)ethan-1-ol
