Perylenediimide-based metal-organic frameworks: structural, electrochemical and spectroelectrochemical...

Area of Science:

• Materials Science
• Electrochemistry
• Supramolecular Chemistry

Background:

• Metal-organic frameworks (MOFs) offer tunable properties for various applications.
• Perylene diimide (PDI) derivatives are known for their unique electronic and optical characteristics.
• Integrating PDI into MOFs can lead to novel functional materials.

Purpose of the Study:

• To synthesize and characterize novel MOFs incorporating a functionalized PDI ligand.
• To investigate the electrochemical and spectroelectrochemical behavior of these PDI-based MOFs.
• To demonstrate the electrochromic properties arising from the PDI moiety within the MOF structure.

Main Methods:

• Ligand functionalization for solubility.
• Synthesis of cobalt dicarboxylate paddlewheel MOFs.
• Electrochemical analysis (cyclic voltammetry).
• Spectroelectrochemical measurements (UV-Vis spectroscopy).

Main Results:

• Successful synthesis of two PDI-based MOFs with cobalt dicarboxylate units.
• Demonstration that the MOF structure preserves the electrochemical and optical properties of the PDI ligand.
• Observation of electrochromic behavior in the synthesized PDI-MOFs.

Conclusions:

• The developed PDI-based MOFs are promising functional materials.
• The MOF framework effectively maintains the desirable properties of the PDI unit.
• These findings open avenues for electrochromic devices based on MOFs.
