Claims20
A polymer comprising repeat units, wherein the repeat units have a structure of Formula (I):
- wherein:
- each R1 is independently selected from the group consisting of H, an electron withdrawing group, and an electron donating group;
- each R2 is independently selected from the group consisting of H, an electron withdrawing group, and an electron donating group;
- R3 is H, an electron withdrawing group, or an electron donating group;
- R4 is H, an electron withdrawing group, or an electron donating group;
- R5 is H, an electron withdrawing group, or an electron donating group;
- each W1 is independently O or NR6, wherein each R6 is independently H or optionally substituted alkyl;
- m is 3;
- and
- n is 3.
