ABSTRACT:
An electronic device comprising a semiconductor layer in contact with a number of electrodes, wherein the semiconductor layer includes a small molecular thiophene compound consisting of a plurality of thiophene units, each thiophene unit being represented by structure (A)wherein each thiophene unit is bonded at either or both of the second ring position and the fifth ring position, wherein there is at least one thiophene unit where R1is present at the third ring position or the fourth ring position, or at both the third ring position and the fourth ring position, wherein for any two adjacent thiophene units there is excluded the simultaneous presence of the same or different R1at the 3-position of one thiophene unit and at the 3′-position of the other thiophene unit.
