Abstract
A semiconducting composition comprising a semiconducting polymer and a semiconducting non-polymeric polycyclic compound, wherein the semiconducting polymer comprises units of A and/or B: wherein R1, R2, R5, R6, R7, R8, x, y, p, q, r, R3, R4, R9, R10 and R11 have any of the meanings defined in the description.

A semiconducting composition comprising a semiconducting polymer and a semiconducting non-polymeric polycyclic compound, wherein the semiconducting polymer comprises units of A and B:
- wherein R1, R2, R5, R6, R7 and R8 are each independently selected from C1-C12 alkyl, C2-C12 alkenyl and aryl;
- wherein when any R1, R2, R5, R6, R7 and/or R8 group is C1-C12 alkyl or C2-C12 alkenyl, then each R1, R2, R5, R6, R7 and/or R8 group is optionally substituted by one or more substituents independently selected from cyano, hydroxy, C1-C10 alkoxy, C3-C8 cycloalkyl, heterocyclyl, aryl and a group of the formula —(OCH2CH2)z—OR12, wherein z is 1, 2, 3, 4, 5 or 6 and R12 is C1-C4 alkyl;
- and wherein any aryl group present in R1, R2, R5, R6, R7 and/or R8 is optionally substituted by one or more substituents independently selected from C1-C4 alkyl, C1-C4 alkoxy, cyano, hydroxy, fluoro, chloro, trifluoromethyl and trifluoromethoxy;
- wherein in the units A (when present) at least one of the R1 and R2 groups is substituted by one or more cyano groups and in the units B (when present) at least one of the R5, R6, R7 and R8 groups is substituted by one or more cyano groups;
- x represents 0, 1, 2 or 3;
- y represents 0, 1, 2 or 3;
- p represents 0, 1, 2 or 3;
- q represents 0, 1 or 2;
- r represents 0, 1, 2 or 3;
- wherein each R3, R4, R9, R10 and R11 (when present) is independently selected from C1-C6 alkyl and C1-C4 alkoxy.
