Figure 14

(a) Scanning electron microscope (SEM) images of randomly oriented fibers of hexapentyloxytriphenylene (HPT); (b) fibers formed by HPT-gold nanorod composites and (c) dark field STEM images of gold nanorods embedded in HPT nanoribbons. The bright spots in the fibers represent the gold nanorods embedded in the ribbon with their longitudinal axis parallel to the length of the ribbon.83
