Abstract

A composition and method of forming a composition including a compound including a poly(phenylene) backbone represented by the following formula:

wherein each of R 1 , R 2 and R 3 may be the same or different and is H or an unsubstituted or inertly-substituted aromatic moiety; wherein Ar 1 is an unsubstituted or inertly-substituted aromatic moiety; wherein R 4 is an alkylene, perfluoroalkyl, polyethylene glycol, or polypropylene glycol moiety; wherein each of R 6 , R 7 , R 8 , R 9 , R 10 and R 11 is H or a monovalent hydrocarbon group including two to 18 carbon atoms, with the proviso that each R 6 , R 7 , R 8 , R 9 , R 10 and R 11 cannot be H; and wherein each of Y 6 , Y 7 , Y 8 , Y 9 , Y 10 and Y 11 may be the same or different and is H or a functional group are disclosed. The composition can be used as anion-exchange membranes and as an electrode binder material in anion exchange membrane fuel cells.

First claim

What is claimed is:

1. A composition comprising:
a poly(phenylene alkylene) backbone-containing compound, oligomer or polymer represented by the following formula:

wherein each of R 1 , R 2 and R 3 may be the same or different and is H or an unsubstituted or inertly-substituted aromatic moiety;
wherein Ar 1 is an unsubstituted or inertly-substituted linking moiety;
wherein R 4 is an alkylene, perfluoroalkylene, polyethylene glycol, or polypropylene glycol moiety;
wherein at least one of R 6 , R 7 , R 8 , R 9 , R 10 and R 11 is a saturated hydrocarbon group comprising two to 18 carbon atoms and remaining members of the group R 6 , R 7 , R 8 , R 9 , R 10 and R 11 are H; and
wherein each of Y 6 , Y 7 , Y 8 , Y 9 , Y 10 and Y 11 present when R 6 , R 7 , R 8 , R 9 , R 10 and R 11 is a saturated hydrocarbon group comprising two to 18 carbon atoms may be the same or different and is H or a functional group.

2. The composition of claim 1 , wherein either one or both of R 1 and R 2 comprises an acyl group and the side chain is attached to the at least one of the plurality of rings through the acyl group.

3. The composition of claim 1 , wherein one or more of R 6 , R 7 , R 8 , R 9 , R 10 and R 11 comprises an alkylene group comprising two to 18 carbon atoms.

4. The composition of claim 1 , wherein one or more of Y 6 , Y 7 , Y 8 , Y 9 , Y 10 and Y 11 when present comprises a nitrogen containing base.

5. The composition of claim 1 , wherein one or more of Y 6 , Y 7 , Y 8 , Y 9 , Y 10 and Y 11 when present comprises a nitrogen containing resonant stabilized cation group.

6. A membrane comprising the composition of claim 1 .

7. An electrode comprising the composition of claim 1 .
