NEW MATERIAL:A polyether derivative shown by the formulaI(R<1>-R<3> are H or alkyl). EXAMPLE:1-(3'-o-Carboxylphenoxypropoxy)-2-(3'-8''-quinolinoxypropoxy)- 4-t-butylbenzene. USE:An ionophore (cation transfer agent). Showing selective transfer ability especially to lithium ion, capable of transporting a cation by sending it to a concentration gradient. PROCESS:A polyether derivative shown by the formula II (R<4> is protective group for reaction) is hydrolyzed in an alkali condition at 60-80 deg.C, and neutralized with an organic or an inorganic acid, to give a compound shown by the formulaI. |
