Abstract:Conjugated polymer brush (CPB) films are more robust and exhibit more vertically aligned polymer chains than their spun‐cast analogs. We prepare CPB films of poly(3‐hexylthiophene) (P3HT) by coupling an amine‐terminated surface (ATS) formed from (3‐aminopropyl)triethoxysilane (APTES) on Si/SiO2 to 4‐bromobenzoic acid using standard, inexpensive peptide coupling reagents. The resulting terminal bromobenzene is reacted with Pd(PtBu3)2 and immersed in the monomer solution. X‐ray photoelectron spectroscopy, spectr… Show more
