title: Chemical-Bonding-Directed Hierarchical Assembly of Nanoribbon-Shaped Nanocomposites of Gold Nanorods and Poly(3-hexylthiophene).
abstract: Nanoribbon-shaped nanocomposites composed of conjugated polymer poly(3-hexylthiophene) (P3HT) nanoribbons and plasmonic gold nanorods (AuNRs) were crafted by a co-assembly of thiol-terminated P3HT (P3HT-SH) nanofibers with dodecanethiol-coated AuNRs (AuNRs-DDT). First, P3HT-SH nanofibers were formed due to interchain π-π stacking. Upon the addition of AuNRs-DDT, P3HT-SH nanofibers were transformed into nanoribbons decorated with the aligned AuNRs on the surface (i.e., nanoribbon-like P3HT/AuNRs nanocomposites). Depending on the surface coverage of the P3HT nanoribbons by AuNRs, these hierarchically assembled nanocomposites exhibited broadened and red-shifted absorption bands of AuNRs in nIR region due to the plasmon coupling of adjacent aligned AuNRs and displayed quenched photoluminescence of P3HT. Such conjugated polymer/plasmonic nanorod nanocomposites may find applications in fields, such as building blocks for complex superstructures, optical biosensors, and optoelectronic devices.
