Promoting photocatalytic CO₂ reduction through facile electronic modification of N-annulated perylene diimide rhenium bipyridine dyads.

ABSTRACT: The development of CO₂ conversion catalysts has become paramount in the effort to close the carbon loop. Herein, we report the synthesis, characterization, and photocatalytic CO₂ reduction performance for a series of N-annulated perylene diimide (NPDI) tethered Re(bpy) supramolecular dyads [Re(bpy-C2-NPDI-R)], where R = -H, -Br, -CN, -NO₂, -OPh, -NH₂, or pyrrolidine (-NR₂). The optoelectronic properties of these Re(bpy-C2-NPDI-R) dyads were heavily influenced by the nature of the R-group, resulting in significant differences in photocatalytic CO₂ reduction performance. Although some R-groups (i.e. -Br and -OPh) did not influence the performance of CO₂ photocatalysis (relative to -H; TON_co ∼60), t
