Compared to block copolymers, there have been relatively fewer examples of using homopolymers for nanofabrication. Nevertheless, some polymers with amphiphilic properties were also used in the fabrication of nanostructures with various metal salts/complexes. For example, polyaniline (PANI) emeraldine base formed self-organized mesomorphic structures when mixed with Zn(DBS)2 by the coordination between Zn2+ and the imine nitrogen atoms on the polymer main chain.100 The resulting supramolecule PANI[Zn(DBS)2]0.5 had a comb-shaped... 

The stereocomplex formed from complementary strands of isotactic and syndiotactic poly(methyl methacrylate)s (it- and st-PMMAs) with an it st-stoichiometry of 1 2 represents another class of unique, polymer-hased helical supramolecules suitable for AFM studies. Although this stereocomplex has heen known for half a century, the molecular basis of the stracture and the mechanism of complex formation are still under dehate. In 1989, Schomaker and Challa proposed a double-stranded helix model for the stereocomplex based on the wide angle X-ray scattering (WAXS) analysis of the stretched fiber, which is composed of a 9i it-PMMA helix (nine repeating MMA units per turn) strrrormded hy an 18i st-PMMA helix, resulting in a double-stranded helix with a helical pitch of 1.84 nm. To verify the stmcture of the PMMA stereocomplex by the AFM technique, Kumaki et al. prepared a mixed monolayer of it- and...
