Abstract
The present disclosure relates to compositions including a first polymeric structure having a structure of Formula (I), (II), (III), (IV), or (V): or a salt thereof, and a second polymeric structure having a structure of Formula (X) or Formula (XI): or a salt thereof, in which at least one of these can include an ionizable moiety or an ionic moiety, for use in an electrochemical cell. Materials, devices, and methods using such compositions are also described.
Claims21
A composition comprising a first structure and a second structure, wherein:
- (i) the first structure comprises:
- or a salt thereof, wherein:
- each of R7′ and R8′ is, independently, an electron-withdrawing moiety, H, optionally substituted aliphatic, optionally substituted alkyl, optionally substituted heteroaliphatic, optionally substituted heteroalkyl, optionally substituted aromatic, optionally substituted aryl, or optionally substituted arylalkylene, wherein at least one of R7′ or R8′ comprises the electron-withdrawing moiety or wherein R7′ and R8′ can be taken together to form an optionally substituted cyclic group;
- each of R9′ and R10′ is, independently, H, optionally substituted aliphatic, optionally substituted alkyl, optionally substituted heteroaliphatic, optionally substituted heteroalkyl, optionally substituted aromatic, optionally substituted aryl, or optionally substituted arylalkylene, or wherein R9′ and R10′ can be taken together to form an optionally substituted cyclic group;
- Ar comprises or is an optionally substituted aromatic or optionally substituted arylene;
- n is an integer of 1 or more;
- and
- each of ring a1, ring b1, and/or ring c1 can be optionally substituted;
- wherein one or more of ring a1, ring b1, ring c1, R7′, R8′, R9′, and R10′ comprises an ionizable moiety or an ionic moiety;
- and
- (ii) the second structure comprises:
- or a salt thereof, wherein:
- each of R9 and R10 is, independently, an electron-withdrawing moiety, H, optionally substituted aliphatic, optionally substituted alkyl, optionally substituted heteroaliphatic, optionally substituted heteroalkyl, optionally substituted aromatic, optionally substituted aryl, optionally substituted aryloxy, or optionally substituted arylalkylene, wherein R9 and R10 can be taken together to form an optionally substituted cyclic group;
- m is an integer of 1 or more;
- q is 0, 1, 2, or more;
- each of rings a, b, and c is optionally substituted;
- and
- wherein one or more of rings a, b, and c and R9 and R10 optionally comprises an ionizable moiety or an ionic moiety.
