One of many popular alkylated thiophenes used as a building block

Adds solubility to the target molecules in application of OFETs and OPVs. The alkyl chain can also adjust the film morphology in film.


2-Decylthiophene 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].
