Abstract

The present invention relates to a compound of formula 1 and an organic electronic device comprising an organic semiconductor layer, wherein at least one organic semiconductor layer comprises a compound of formula (1), wherein X is selected from O, S or Se; Ar1 is selected from unsubstituted or substituted C2 to C60 heteroarylene, and wherein the substituted C2 to C60 heteroarylene comprises at least about one to about six substituents, wherein the substituent of the substituted C2 to C60 heteroarylene are independently selected from C1 to C12 alkyl, C1 to C12 alkoxy, CN, OH, halogen, C6 to C36 arylene, or C2 to C25 heteroarylene; n is 1 or 2; L1 is selected from a single bond, C1 to C4 alkyl, substituted or unsubstituted C6 to C36 arylene, wherein the substituent of substituted C6 to C36 arylene is selected from C1 to C12 alkyl, C6 to C18 arylene; L2 is selected from a single bond or C1 to C6 alkyl; R1, R2 are independently selected from substituted or unsubstituted C1 to C16 alkyl, wherein the substituent of substituted C1 to C16 alkyl is selected from C6 to C18 arylene or C2 to C12 heteroarylene; wherein the compound of formula 1 comprises at least about 4 of C6-arylene rings an…
