ORGANIC SEMICONDUCTING POLYMERS

Abstract:

A polymer comprising: ##STR00001## In this polymer W is selected from the group consisting of: S, Se, O, and N-Q. Additionally, Q is selected from the group consisting of: a straight-chain carbyl, silyl or hydrocarbyl, branched, cyclic alkyl with 1 to 30 atoms, and fused aromatic rings. In this polymer, R1, and R4 are independently selected from the group consisting of: F, Cl, I, Br, CN, --NCO, --NCS, --OCN, --SCN, --OX, --SX, --NH2, --C(.dbd.O)X, --C(.dbd.O)--OX, --OX, --NHX, --NXX', --C(.dbd.O)NHX, --C(.dbd.O)NXX', --SO3X, --SO2X, --OH, --NO2, CF3, --SF5, a straight-chain or branched carbyl, silyl, or hydrocarbyl, a branched or cyclic alkyl with 1 to 30 atoms, a fused substituted aromatic ring, and a fused unsubstituted aromatic ring. Additionally, R.sub.2 and R.sub.3 are independently selected from F, Cl, Br and I. In this polymer, the fused aromatic rings can be independently fused with groups consisting of: a straight-chain or branched carbyl, silyl, or hydrocarbyl, a branched or cyclic alkyl with 1 to 30 atoms, a fused substituted aromatic ring, and a fused unsubstituted aromatic ring and wherein h+j is between 0.2 to 0.6 and i+k is between 0.4 and 0.8
