2-Decylthiophene (CAS number 4861-61-4) with a dodecyl (C₁₂H₂₅) carbon hydrate side chain, is an useful alkylated thiophene that is commonly used as an intermediate for the construction of semiconducting polymers or small molecules for device fabrication of organic field-effect transistors and polymer solar cells.

PTVTTT2T, a copolymer with a backbone of biaxially 2-dodecylthiophene side chained thieno[3,2-b]thiophene (TT2T) and thienylene-vinylene-thienylene (TVT), possessed better molecular packing in thin films with a nanofiber structure owing to its coplanar backbone and the optimum side chain length for solubility and film morphology. The average field-effect charge mobility of PTVTTT2T was found to be 0.64 cm² V^-1 s^-1 with a high on/off ratio over 10⁷ under ambient environment for over three months.
