Isoreticular two-dimensional magnetic coordination polymers prepared through pre-synthetic ligand functionalization.

Area of Science:

• Materials Science
• Chemistry
• Physics

Background:

• Chemical functionalization tailors properties of 2D materials.
• Post-synthetic methods often disrupt the long-range structural order of 2D materials.

Purpose of the Study:

• To present a pre-synthetic approach for creating functionalized 2D materials.
• To isolate crystalline, robust, and magnetic functionalized monolayers of coordination polymers.

Main Methods:

• Preparation of five isostructural layered magnetic coordination polymers using Fe(II) and benzimidazole derivatives.
• Mechanical exfoliation of the coordination polymers to obtain 2D materials.

Main Results:

• Isolation of crystalline, robust, and magnetic functionalized monolayers.
• The 2D materials retained their long-range structural order.
• The materials exhibited good mechanical and magnetic properties.

Conclusions:

• The pre-synthetic approach enables the creation of ordered, functionalized 2D magnetic materials.
• These materials are suitable for exploring 2D magnetism and developing gas sensors.
