2-Decylthiophene (CAS number 24769-39-9) is one of the many popular alkylated thiophenes that are used as building blocks for the synthesis of semiconducting small molecules, oligomers and polymers in application of polymer solar cells and organic field-effect transistors. 2-Decylthiophene has thiophene structure with a decyl group (C10H21) at 2-position.

Fabricated device based on piceno[4,3-b:9,10-b′]dithiophene with two decyl end groups (C10-PiDT) shows typical p-type characteristics under ambient conditions in the dark. The best hole mobilities under the optimized FET parameters showed an excellent hole mobility of 1.21 cm2 V-1 s-1 [1].
