Abstract:
A new poly(3‐butylthiophene) derivative with one terminus functionalized with a 1H,1H,2H,2H,3H,3H‐perfluoroundecyl group (P3BT‐F17) is synthesized by Ni‐catalyzed quasi‐living polymerization and the subsequent quenching of living ends by allyl‐Grignard reagent and the attachment of a fluoroalkyl chain. The quantitative introduction of fluoroalkyl chain ends is confirmed by matrix‐assisted laser desorption/ionization time‐of‐flight–mass spectrometry (MALDI‐TOF‐MS), gel‐permeation chromatography (GPC), 1H NMR spectroscopy, and X‐ray photoelectron spectroscopy (XPS). The electronic properties of P3BT‐F17 in solution and its crystalline structure in the solid state are investigated by UV–vis spectroscopy and cyclic voltammetry (CV), and by DSC and X‐ray diffraction (XRD) analyses.
