Abstract: The present invention generally relates to a method for preparing structurally unique nanomaterials and the products thereof. In particular, the present invention discloses a method for preparing an array of ultra-narrow nanowire or nanorod on a patterned monolayer supported by a 2D material substrate in a controlled environment, wherein said pattered monolayer comprises a polymerizable amphiphiles such as phospholipid with a terminal amine and wherein said controlled environment comprises a major nonpolar solvent, a trace amount of polar solvent, and a unsaturated aliphatic amine. Gold nanowires (AuNWs) so prepared have a highly controlled diameter of about 2 nm, a length up to about 1000 nm, and an AuNW ordering over an area >100 μm2.

Abstract: The present invention generally relates to a method for creating a chemically structured surface with structural elements as small as 1 nm, on a material that does not itself display a high degree of ordering, using thin molecular layers that minimize the material added through the coating. In particular, the present invention discloses a method for assembling a chemical pattern on a surface, comprising pattern elements with scales that can be as small as 1 nm, and then transferring that pattern to another substrate, on which the pattern would not form natively. In the described method, the patterned monolayer is comprised of polymerizable amphiphiles such as diyne phospholipids or diynoic acids, which are transferred from the ordering substrate using a transferring material such as poly(dimethylsiloxane).

Abstract: This invention generally relates to a method for modulating interfacial wettability of a noncovalent nanoscopic monolayer or thin film. Particularly, this invention relates to a method for modulating interfacial wettability of a two-dimensional (2D) material using a molecular layer prepared from a polymerizable amphiphilic monomer having a hydrophilic head and a hydrophobic tail, wherein enhanced or decreased wettability of said 2D material is achieved by proper allocating the position of polymerizable group relative to the hydrophilic head and the hydrophobic tail.

Abstract: This invention generally relates to a method for preparing and transferring a monolayer or thin film. In particular this present invention is an improved version of the Langmuir-Schaefer technique for preparing and transferring a monolayer or thin film, incorporating in situ thermal control of the substrate during the transfer process.
