Polymers

Polymers

The word polymer is derived from the Greek words “poly” which means “many” and “mer” which means “parts”. Polymers are long chains of molecules composed of repeating units of smaller molecules, known as monomers. They either occur naturally, such as DNA and proteins, or can be constructed synthetically, like plastics. They have varied structural characteristics, such as linear chains, branched chains, or complex networks, that contribute to the...

Protein-protein Interfaces

Protein-protein Interfaces

Many proteins form complexes to carry out their functions, making protein-protein interactions (PPIs) essential for an organism's survival. Most PPIs are stabilized by numerous weak noncovalent chemical forces. The physical shape of the interfaces determines the way two proteins interact. Many globular proteins have closely-matching shapes on their surfaces, which form a large number of weak bonds. Additionally, many PPIs occur between two helices or between a surface cleft and a...

States of Water

States of Water

Water exists in any one of the three classical states: solid (ice), liquid (water), and gas (steam or water vapor). The state of water depends on i) the intermolecular forces that draw molecules together and ii) the kinetic energy that leads to movements that pull them apart.
Water freezes when the intermolecular forces are greater than the kinetic energy. Unlike most other substances, water is less dense in its solid state than in its liquid state. This is because each water molecule can form...

Air-entraining Agents

Air-entraining Agents

Air-entraining agents improve the durability and workability of concrete in climates with frequent freezing and thawing. These agents prevent cracks by introducing small air bubbles into the mix, creating spaces accommodating water expansion when temperatures drop. The air-entraining agents lower the surface tension of water, forming stable, small air bubbles. This method is more effective than having accidental large voids, as the intentional, smaller, and evenly distributed air voids improve...

Background:

Two-dimensional (2D) polymers are advanced materials with unique properties derived from their atomic-scale thickness.
Synthesizing ordered 2D polymers under ambient conditions remains a significant challenge in materials science.
Triptycene-based monomers offer potential for creating well-defined polymer architectures.

Purpose of the Study:

To synthesize a long-range-ordered 2D polymer from a novel trifunctional, partially fluorinated anthracene-substituted triptycene monomer.
To characterize the structural properties and confirm the 2D polymer formation under ambient conditions.
To investigate the potential of air/water interface polymerization for creating ordered nanostructures.

Main Methods:

Spreading of the triptycene monomer as a monolayer at the air/water interface.
UV irradiation to induce polymerization and form the 2D polymer network.
Analysis using Brewster angle microscopy (BAM), scanning tunneling microscopy (STM), and non-contact atomic force microscopy (nc-AFM).

Main Results:

Successful synthesis of a long-range-ordered 2D polymer network.
Structural analysis confirmed lattice parameters consistent with a model derived from X-ray diffractometry.
nc-AFM images revealed long-range order over areas exceeding 300×300 nm², with monodisperse pore sizes.

Conclusions:

A novel 2D polymer has been successfully synthesized under ambient conditions at an air/water interface.
The study provides definitive structural evidence for the formation of a 2D polymer network.
Air/water interface polymerization is a viable method for creating ordered, nanostructured 2D polymers.
