“…Structural differences between dendronized PMA and PS were not significant. Direct visualization of these highly "photogenic" 449 molecules on surfaces was also performed, confirming cylindrical organization without interpenetration of the side groups (Figure 103). 450,451 Calculation of the persistence length a′ and Kuhn length l k indicates extremely stiff polymers with values intermediate between PMA-g-PS obtained via PS macromonomers with MW )1740 and 2740, respectively, 452 and far greater than those obtained for PMA jacketed with Fre ´chet-type dendrons.…”

The synthesis of 2-[3,4-bis(n-alkan-1-yloxy)phenyl]-2-oxazolines with alkan = octan, decan, dodecan, and tridecan is presented. Their living cationic ring opening polymerization produces cylindrical macromolecules that self-organize in a hexagonal columnar two-dimensional phase. The structural analysis of these polymers was carried out by a combination of techniques including differential scanning calorimetry, thermal optical polarized microscopy, X-ray diffraction, transmission electron microscopy, electron diffraction, scanning force microscopy, and atomic force microscopy (AFM). The diameter of these cylindrical macromolecules ranges from 33 to 44 A, and therefore they represent the simplest cylindrical macromolecules that can be directly visualized by AFM on a surface. Preliminary experiments have demonstrated the use of these cylindrical macromolecules as models to investigate the creation of two-dimensional and three-dimensional order via direct visualization and thus they represent the simplest nonbiological systems that mimic the role played by the complexes of nucleic acids with proteins in structural analysis by direct visualization.

“…Though interesting results have been obtained using other methods, , scanning tunneling microscopy (STM) remains unparalleled in its ability to resolve molecular-sized structures and to track the translational movement of nanoscale objects . To this end, various groups have synthesized landers, wheelbarrows, , nanowalkers, and polyaromatic systems for the purpose of observing their behavior on metallic surfaces.…”

Synthesis of Fluorescent Dye-Tagged Nanomachines for Single-Molecule Fluorescence Spectroscopy

In an effort to elucidate the mechanism of movement of nanovehicles on nonconducting surfaces, the synthesis and optical properties of five fluorescently tagged nanocars are reported. The nanocars were specifically designed for studies by single-molecule fluorescence spectroscopy and bear a tetramethylrhodamine isothiocyanate fluorescent tag for excitation at 532 nm. The molecules were designed such that the arrangement of their molecular axles and p-carborane wheels relative to the chassis would be conducive to the control of directionality in the motion of these nanovehicles.
