Spatially programmed regioisomeric conjugated microporous polymers modulating zinc sites for selective CO₂ photoreduction to CH₄.

ABSTRACT: Conjugated microporous polymers show great potential for photocatalytic CO₂ reduction into value-added products. However, their catalytic activity and selectivity remain significantly limited due to poor charge separation efficiency and the lack of suitable active sites. Herein, we propose a topology-driven dipole programming strategy that synergistically decouples atomic-level electronic configuration control from spatially resolved active site engineering. Crucially, the regioisomer-dependent π-topology governs light-harvesting ability, dipole polarization hierarchy, and directional charge transport networks. As a result, the designed Zn-TPA-BPy-1, featuring dipole polarization fields and Zn-N₂O₂ sites, exhibits exceptional photocatalytic CO₂ c
