Claim 15:
16. A polymer blend, comprising:
at least one organic semiconductor (OSC) polymer and at least one photosensitizer,
wherein the at least one OSC polymer comprises a structure of Formula 7:, wherein in Formula 7:
Acceptor 1 and Acceptor 2 are each electron withdrawing groups;
Donor 1 and Donor 2 are electron-donating groups;
a and b are, independently, integers greater than or equal to one;
R1, R2, R3, R4, R5, R6, R7, and R8, may be, independently, hydrogen, substituted or unsubstituted C4 or greater alkyl, substituted or unsubstituted C4 or greater alkenyl, substituted or unsubstituted C4 or greater alkynyl, or C5 or greater cycloalkyl,
wherein:
(i) at least one of R1 or R2; one of R3 or R4; one of R5 or R6; and one of R7 or R8 is a substituted or unsubstituted alkyl, substituted or unsubstituted alkenyl, substituted or unsubstituted alkynyl, or cycloalkyl;
(ii) if any of R1, R2, R3, or R4 is hydrogen, then none of R5, R6, R7, or R8 are hydrogen;
(iii) if any of R5, R6, R7, or R8 is hydrogen, then none of R1, R2, R3, or R4 are hydrogen;
(iv) one of R1 or R2 and one of R3 or R4 are, independently, connected with Acceptor 1 and Acceptor 2;
(v) one of R5 or R6 and one of R7 or R8 are, independently, connected with Donor 1 and Donor 2; and
(vi) the at least one OSC polymer has a molecular weight of greater than 10,000,, wherein the polymer blend further comprises at least one crosslinker selected from, , or combinations thereof, wherein n represents the number of repeating units in crosslinker C2, C3 or C4.
