NEW MATERIAL:The amphipathic azacrown compound complex consisting of a transition metal salt of the compound of formula I (R is ≥3C alkyl; n is positive integer).
EXAMPLE: The nickel nitrate complex of the azacrown compound of formula II.
USE: Utilizable widely as a surfactant, a surface-treating agent, or a selective permeable membrane having high permeation performance or a sensor attached to various electrodes and produced by spreading the compound on a water surface, and transferring the ultrathin film of the molecular order thickness on a substrate plate.
PREPARATION: The above complex can be produced by reacting the compound of formula I with a transition metal salt such as nickel chloride, cobalt chloride, ferric chloride, nickel nitrate, cobalt nitrate, ferric nitrate, etc., or their hydrates in an alcohol. Since hydrophobic property is imparted to the hydrophilic azacrown compound to obtain an amphipathic nature by the alkylation of the α-site of the malonic acid group, the obtained compound is expected to be useful over a wide application field.
