Two-dimensional polymers with versatile functionalities via gemini monomers

Area of Science:

• Polymer Chemistry
• Materials Science

Background:

• Two-dimensional synthetic polymers (2DSPs) are sheet-like macromolecules with potential applications.
• Previous synthesis methods required monomers to maintain crystallinity, limiting control over 2DSP size, shape, and functionality.

Purpose of the Study:

• To develop a novel synthetic strategy for producing 2DSPs that bypasses the need for monomer crystallinity.
• To demonstrate the preparation of 2DSPs with controlled characteristics and diverse functionalities.

Main Methods:

• Utilized free radical copolymerization of amphiphilic gemini monomers and their derivatives.
• Arranged monomers in a bilayer at solid-liquid interfaces on various solid templates.
• Employed templates with diverse surface curvatures and dimensions.

Main Results:

• Successfully synthesized 2DSPs with well-controlled size and shape.
• Achieved diverse functionalities in the resulting 2DSPs.
• Demonstrated remarkable mechanical strength of the synthesized 2DSPs.

Conclusions:

• The developed strategy obviates the need for monomer crystallinity in 2DSP synthesis.
• This approach significantly expands the accessible chemistry, morphology, and functionality of 2DSPs.
• The synthesized 2DSPs show promise for applications including nanolithographic resists and antibacterial agents.
