NEW MATERIAL:A compound shown by formula IV [R is group shown by formula V (n is 7-13); X is 6-11C hydrocarbon group and may contain double bond, triple bond or ether chain at any position; Y is hydrophilic group].
EXAMPLE: A compound shown by formula VI.
USE: Useful for producing a compound thin film which has a fluorocarbon chain having excellent hydrophobic nature and a hydrocarbon chain having excellent high orientation at the same time as hydrophobic part of synthetic bimolecule film forming lipid, can use a wide range of organic solvent except water as a solvent to disperse the synthetic lipid and has regular molecular orientation.
PREPARATION: A compound shown by formula I is condensed through dehydration with L-glutamic acid in the presence of a catalyst such as sulfuric acid under heating to form a compound shown by formula II (Q is p-toluenesulfonium ion or sulfate ion) and then active hydrogen group of -NH2 group of the compound shown by formula II is converted into any of various kinds of hydrophilic groups Y to readily give a compound shown by formula IV.
