Construction of Modifiable Phthalocyanine-Based Covalent Organic Frameworks with Irreversible Linking for Efficient Photocatalytic CO₂ Reduction.

ABSTRACT: Covalent organic frameworks (COFs) are considered promising catalysts for photocatalytic CO₂ reduction reaction (pCO₂RR) due to facilitated regulations. However, the instability of COFs with dynamic reversible covalent bonds and the limited modifiability of COFs with irreversible covalent bonds restricted the enhancement of the pCO₂RR performance. Herein, three phthalocyanine-based COFs with ether-linked, CoOP, CoPOP, and CoBOP, were successfully prepared via in situ polycondensation using modifiable bis-phthalonitrile. CoBOP achieved a record of syngas performance in pCO₂RR systems with photosensitizers and sacrificial agents (CO 83.7 mmol g^-1 h^-1 and H₂ 54.7 mmol g^-1 h^-1), surpassing most C
