Abstract
Disclosed are conjugated polymers based on terthiophene. Such polymers exhibit good solubility and great solution processibility, and that enable highly efficient OPVs.
Claims14
A conjugated polymer containing 5 or more repeating units of Formula (I):
- wherein Ar is an aromatic unit that is not thiophene and comprises at least one N atom, wherein there are three thiophene units between each Ar unit;
- X is S or Se;
- M1, M2, M3, M4 are independently selected from H or F;
- and
- R1 and R2 are independently selected from straight-chain, branched or cyclic alkyl groups with 2-40 C atoms, in which one of more non-adjacent C atoms are optionally replaced by —O—, —S—, —C(O)—, —C(O—)—O—, —O—C(O)—, —O—C(O)—O—, —CR0=CR00- or —C≡C— and in which one or more H atoms are optionally replaced by F, Cl, Br, I or CN, or denote aryl, heteroaryl, aryloxy, heteroaryloxy, arylcarbonyl, heteroarylcarbonyl, arylcarbonyloxy, heteroarylcarbonyloxy, aryloxycarbonyl or heteroaryloxycarbonyl having 4 to 30 ring atoms that is unsubstituted or substituted by one or more non-aromatic groups.

A conjugated polymer containing 5 or more repeating units of Formula (II):
- wherein Ar1 and Ar2 are aromatic units that are not thiophene and respectively comprise at least one N atom, Ar1 and Ar2 are different from each other;
- M5, M6, M7, M8, M9, M10, M11, M12 are independently selected from H or F;
- and
- R1 and R2 are independently selected from straight-chain, branched or cyclic alkyl groups with 2-40 C atoms, in which one of more non-adjacent C atoms are optionally replaced by —O—, —S—, —C(O)—, —C(O—)—O—, —O—C(O)—, —O—C(O)—O—, —CR0=CR00- or —C≡C— and in which one or more H atoms are optionally replaced by F, Cl, Br, I or CN, or denote aryl, heteroaryl, aryloxy, heteroaryloxy, arylcarbonyl, heteroarylcarbonyl, arylcarbonyloxy, heteroarylcarbonyloxy, aryloxycarbonyl or heteroaryloxycarbonyl having 4 to 30 ring atoms that is unsubstituted or substituted by one or more non-aromatic groups.
