We report the preparation of chiral polymer nanotubes bearing terthiophene and BINOL units [(
S)-TBOH-PNTs] and the encapsulation of metal nanoparticles (NPs) therein. The monomer, (
S)-TBOH, was synthesized by coventional methods and electrochemically polymerized using porous alumina with a pore diameter of 200 nm on a platinum electrode. The electrolyte solution contained 7mM monomer [(
S)-TBOH] and 0.1M Bu
4NPF
6 in CH
2Cl
2. A voltage of 1.00 V was applied for polymerization. The porous alumina was removed by dissolving in NaOH. The UV-vis spectrum of the PNTs in C
2HCl
2 exhibited a broad absorption peak at 425 nm which is ascribed to the polythiophene. The CD spectra of (S)-TBOH-PNTs and (R)-TBOH-PNTs, show intense Cotton effects and a mirror-image relationship. The PNTs and the encapsulated Au NPs in PNTs (Au NPs@(
S)-TBOH-PNTs) were characterized by SEM, TEM and EDX analysis.
