Abstract
Described are a copolymer including a first repeating unit represented by Chemical Formula 1 and a second repeating unit represented by Chemical Formula 2, a thin film transistor including the same, and an electronic device including same. In Chemical Formula 1 or 2, D1, D2, L1 to L4, and R1 to R4 are the same as described in the detailed description.
Claims20
A copolymer, comprising:
- a first repeating unit represented by Chemical Formula 1, and
- a second repeating unit represented by Chemical Formula 2:
- wherein, in Chemical Formula 1 and Chemical Formula 2,
- D1 and D2 are each independently an electron donating moiety,
- L1 to L4 are each independently a single bond, a substituted or unsubstituted C1 to C20 alkylene group, a substituted or unsubstituted C6 to C30 arylene group, a substituted or unsubstituted C3 to C30 divalent heterocyclic group, a fused ring thereof, or any combination thereof,
- R1 and R2 are each independently a substituted or unsubstituted C5 to C50 branched alkyl group,
- one of R3 or R4 is a substituted or unsubstituted C1 to C50 linear alkyl group, and another one of R3 or R4 is a substituted or unsubstituted C5 to C50 branched alkyl group, and
- * is a linking point.

A copolymer, comprising:
- a random arrangement of a first repeating unit quantity of units of a first repeating unit and a second repeating unit quantity of units of a second repeating unit,
- wherein
- the first repeating unit includes a first electron accepting moiety and a first electron donating moiety, the first electron accepting moiety having a symmetric structure,
- the second repeating unit includes a second electron accepting moiety and a second electron donating moiety, the second electron accepting moiety having an asymmetric structure, and
- the second repeating unit quantity is smaller than the first repeating unit quantity in the copolymer.
