Abstract
The present invention relates to anionic exchange polymers including a poly(phenylene) structure. The structure can include any useful cationic moiety. Methods and uses of such structures and polymers are also described herein. In one instance, such polymers are employed to form a solid membrane.
Claims20
A composition comprising a structure having the formula (III):
- or a salt thereof or a form thereof including a counter ion, wherein:
- each RA comprises an aryl group and a cationic functionality, wherein the aryl group is selected from the consisting of an optionally substituted aryl, optionally substituted alkaryl, optionally substituted arylalkoxy, optionally substituted aryloxy, optionally substituted aryloxycarbonyl, optionally substituted aryloyl, optionally substituted arylcarbonylalkyl, optionally substituted arylsulfonyl, and optionally substituted arylsulfonylalkyl;
- each R1 and R3 is, independently, H, halo, cyano, optionally substituted C1-12 alkyl, optionally substituted C1-12 haloalkyl, optionally substituted C1-12 perfluoroalkyl, optionally substituted C1-12 heteroalkyl, RS, RP, RC, or RF, wherein RS is an acidic moiety comprising a sulfonyl group, RP is an acidic moiety comprising a phosphoryl group, RC is an acidic moiety comprising a carbonyl group, and RF is an electron-withdrawing moiety;
- each ArL is, independently, a bivalent linker comprising optionally substituted arylene;
- each ArM is, independently, a bivalent linker comprising optionally substituted arylene;
- each q is, independently, an integer of from 0 to 5, in which each q for R1 is, independently, 0 or 1;
- each a is, independently, an integer of from 0 to 5, wherein at least one a is not 0;
- m is an integer of from about 1 to 1000;
- L′ is a sublink;
- and
- each RL is, independently, a reactive end group,
- wherein at least one RA is disposed on a pendent aryl group of formula (III).

- each ArL is, independently, a bivalent linker comprising optionally substituted arylene;
- each ArM is, independently, a bivalent linker comprising optionally substituted arylene;
- each q is, independently, an integer of from 0 to 5, in which each q for R1 is, independently, 0 or 1;
- each a is, independently, an integer of from 0 to 5, wherein at least one a is not 0;
- each of m and n is, independently, an integer of from about 1 to 1000;
- L is a linking segment;
- and
