Amide linkage engineering in phthalocyanine-based covalent organic frameworks for enhanced photocatalytic CO2 reduction

Key Points

• The central aim is to enhance photocatalytic CO2 reduction using engineered phthalocyanine-based covalent organic frameworks.
• Development of AM-COF through post-synthetic modification of imine to amide linkages.
• Characterization of AM-COF properties and structures.
• Evaluation of photocatalytic performance in CO2 reduction.
• AM-COF achieves a CO2-to-CO conversion rate of 33 mmol•g -1 •h -1.
• The modified linkages improve the efficiency of the photocatalytic process.
