NEW MATERIAL:An anionic cyclophane derivative of the given formula, wherein the carbon number which constitutes X and Y unit is 1-10; the type of the carbon atom is one or a combination selected from the three consisting of carbon atoms having sp, sp<2> or sp<3> hybridized orbitals, and a heteroatom may be contained in the units. USE:It exhibits an excellent function for separation between organic cationic compounds when added to the mobile phase of liquid chromatography in a small amount or when supported on a carrier to be used as a packing for chromatography. PREPARATION:4,4'-Dimethoxy-3,5,3',5'-tetramethoxycarbonyldiphenyl ketone used as a starting material is reduced and the methyl ether linkage is cleaved. Then spacers corresponding to X and Y are reacted with the product, thereby forming a cyclophane skeleton. Then, the ester linkage is hydrolyzed to produce the aimed compound. |
