Semiconductor Polymers

A polymer having a structure of:

• wherein
• R1 and R2 are each independently selected from the group consisting of H, C1-30-alkyl, C2-30-alkenyl, C2-30-alkynyl, C3-10-cycloalkyl, C5-10-cycloalkenyl, 3-14 membered cycloheteroalkyl, C6-14-aryl and 5-14 membered heteroaryl,
• R3, R4, R9, and R10 are each independently hydrogen, or —CN,
• R5, R6, R7, and R8 are each independently hydrogen, a halogen selected from the group consisting of fluorine, chlorine, bromine iodine, and astatine, —CN, —NO2, —OH, —O—CH2CH2O—C1-10-alkyl, —O—COX1, —S—C1-10-alkyl, —NH2, —NHX1, —NX1X2, —NH—COX1, —COOH, —COORS, —CONH2, —CONHX1, —CONX1X2, —CO—H, —COX1, C3-10-cycloalkyl, 3-14 membered cycloheteroalkyl, C6-14-aryl or a 5-14 membered heteroaryl, with the proviso that neither of R5, R6, R7, and R8 are alkoxy groups (—OX1) or at least three or all four of R5, R6, R7, and R8 are alkoxy groups,
• wherein
• X1 and X2 are each independently C1-10-alkyl, C2-10-alkenyl, C2-10-alkynyl, C3-10-cycloalkyl, C5-10-cycloalkenyl, 3-14 membered cycloheteroalkyl, C6-14-aryl and 5-14 membered heteroaryl, and
• n is an integer from 2 to 1000.
