Claims14
A compound for an organic thin film transistor represented by the following formula (1):
- wherein X1s are independently an oxygen atom or a group represented by N—R13;
- R1 to R13 are independently a hydrogen atom, a halogen atom, an alkyl group having 1 to 30 carbon atoms, a haloalkyl group having 1 to 30 carbon atoms, an alkoxy group having 1 to 30 carbon atoms, a haloalkoxy group having 1 to 30 carbon atoms, an alkylthio group having 1 to 30 carbon atoms, a haloalkylthio group having 1 to 30 carbon atoms, an alkylamino group having 1 to 30 carbon atoms, a dialkylamino group having 2 to 60 carbon atoms wherein the alkyl groups may be combined with each other to form a ring structure containing a nitrogen atom, an alkylsulfonyl group having 1 to 30 carbon atoms, a haloalkylsulfonyl group having 1 to 30 carbon atoms, an aryl group having 3 to 60 carbon atoms, an alkylsilyl group having 3 to 20 carbon atoms, an alkylsilylethynyl group having 5 to 60 carbon atoms, an arylamino group having 3 to 60 carbon atoms, a diarylamino group having 6 to 120 carbon atoms or a cyano group, which each may have a substituent;
- and
- when X1s are both groups represented by N—R13, two R13s may be the same or different.
