A process of forming a nanopatterned substrate is provided. The process comprising the steps of first preparing a giant surfactant comprising a cage-like molecular nanoparticle head linked to a polymer chain tail through a chemical linkage. Next, using the giant surfactant, a thin film is formed. Next the thin film formed from the giant surfactant is annealed such that the giant surfactant self-assembles into a desired nanostructure. The desired nanostructure is comprised of periodic major domains and minor domains. Finally, at least some of either the major domain or the minor domain is selectively removed to form the nanopatterned substrate.

Sub-10-nanometer nanostructures engineered from giant surfactants

The preparation of novel fullerynes which are fullerenes (e.g. C, C, C, etc.) that contain one or more alkyne functionalities and may contain additional functional groups such as hydroxyls, halogens, esters, haloesters, phenyl, oligo(ethylene glycol)s, perfluorinated alkyl chains, and the like. Two desired preparation routes are disclosed. The first one is the Fischer esterification in desired solvents using a special designed reactor in contrast to the heretofore initial Steglich reaction that results in side reactions and low yields. The second one uses acetylide Grignard reagents that have reduced nucleophilicity and higher stability in contrast to the use of heretofore initial lithium organyls or other Grignard reagents that would add to Cwith possible multi-additions in an uncontrollable manner.
