Claim 0:
1. A polymer semiconductor material is denoted by structure (PI):, wherein each X is independently selected from oxygen (O), sulphur (S), selenium (Se), or nitrogen (N);
R, and R1 are independently selected from hydrogen, an optionally substituted hydrocarbon with 1 to 60 carbon (C) atoms, cyano (CN), nitro, or a halogen;
R2 is selected from hydrogen or a C1-C60 alkyl optionally substituted with an alkoxy, nitro, or a halogen;
Y is selected from N or —CR″, wherein R″ is H, an optionally substituted hydrocarbon with 1 to 60 carbon (C) atoms, cyano (CN), nitro, or a halogen;
a is an integer from 1 to 20;
each Ar is selected from the group, , wherein R of Ar is hydrogen, an optionally substituted hydrocarbon with 1 to 60 carbon (C) atoms, cyano (CN), nitro, or a halogen, and wherein Ar can be substituted by a member of an optionally substituted hydrocarbon with 1 to 60 carbon (C) atoms, cyano (CN), nitro, or a halogen;
b is an integer from 1 to 20;
n is a number from about 1 to 1,000,000, and wherein * represents a bond to another PI unit or, if terminal, is hydrogen or a halogen group.
