Provided are a novel water-soluble diacetylene monomer, a composition for photolithography including the novel water-soluble diacetylene monomer and a conductive polymer, and a method of forming micropatterns using the composition. The water-soluble diacetylene monomer may not aggregate even when mixed with a water-soluble conductive polymer. Accordingly, a uniform composition for photolithography can be prepared by mixing a water-soluble conductive polymer with the diacetylene monomer, and micropatterns can be formed using the composition. More particularly, when the composition is formed into a thin film and then is irradiated with light, only light-irradiated portions of the diacetylene monomer are selectively crosslinked due to photopolymerization, thereby resulting in insoluble negative-type micropatterns.

The present invention generally relates to a device and a process for performing large-scale noncovalent functionalization of 2D materials, with chemical pattern elements as small as a few nanometers, using thermally controlled rotary Langmuir-Schaefer conversion. In particular, the present invention discloses a device comprising a thermally regulated disc driven by a rotor with fine speed control configured to be operable with a Langmuir trough for performing large-scale noncovalent functionalization of 2D materials, achieving ordered domain areas up to nearly 10,000 m.sup.2, with chemical pattern elements as small as a few nanometers. A process using the device for performing large-scale noncovalent functionalization of 2D materials with chemical pattern elements as small as a few nanometers is within the scope of this disclosure. The process we demonstrate would be readily extensible to roll-to-roll processing, addressing a longstanding challenge in scaling Langmuir-Schaefer transfer for practical applications.

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.
