An aromatic perfluoroalkane monomer is provided that can be used for the manufacture of a polymer membrane for a PEM-type fuel cell. The perfluoroalkane monomer has a structure corresponding to a formula (I):
Z1—Ar3—C(O)—Ar1—(CF2)n—Ar2—C(O)—Ar4—Z2 (I)
in which:
n is in a range from 1 to 20;Ar1, Ar2, Ar3, Ar4 which are identical or different, represent a substituted or unsubstituted phenylene group; andZ1 and Z2, which are identical or different, represent an electrophilic or nucleophilic polymerizable functional group. |

1. An aromatic perfluoroalkane monomer corresponding to a formula (I):
Z1—Ar3—C(═O)—Ar1—(CF2)n—Ar2—C(═O)—Ar4—Z2 (I) in which:
n is in a range from 1 to 20,Ar1, Ar2, Ar3, Ar4 which are identical or different, represent an unsubstituted phenylene group or a phenylene group substituted with at least one substituent selected from the group consisting of —F, —Cl, —Br, —CN, —CF3, —NO2, —N(CH3)2, —COOH, —COOM, —PO3H, —PO3M, —SO3H, —SO3M, hydroxyl, alkyl, cycloaklyl, perfluoroalkyl, sulphoalkyl, sulphoaryl, aryl, alkylcarbonyl, arylcarbonyl, alkoxyl and aryloxyl, where M is an alkali metal cation, andZ1 and Z2, which are identical or different, represent an electrophilic or nucleophilic polymerizable functional group. |
