Abstract
Provided are compositions including a core moiety and a plurality of polymeric units, in which at least one of these can include an ionizable moiety or an ionic moiety. The core moiety may be a multivalent core moiety, trivalent core moiety, tetravalent core moiety, pentavalent core moiety, or multivalent arylene moiety. Materials, electrochemical cells, and methods using such compositions are also described.
Claims14
A composition comprising a structure of the formula:
- or a salt thereof, wherein:
- each of P1, P2, and P3 is independently a structure of any one or more of the following:
- 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 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;
- n is an integer of 1 or more;
- each of ring a, ring b, and/or ring c can be optionally substituted;
- and
- Z is a core moiety;
- and
- at least one of Z, P1, P2 or P3 comprises an ionizable moiety or an ionic moiety.
