Abstract

A rhenium(i) naphthalimide complex [Re(CO)3(5-PAN)Cl] (Re(5-PAN); 5-PAN = 1-(1,10-phenanthroline)-4-nitro-naphthalimide) was synthesized, characterized, and evaluated as a photocatalyst for CO2reduction. Characterization included use of MALDI-ToF mass spectrometry, FT-IR, RAMAN,1H and13C NMR, elemental analysis, electronic absorption and emission spectroscopy, single crystal X-ray diffraction, DFT and cyclic voltammetry. Photocatalytic (406 nm) reduction of13CO2to formate (H13COO) in the presence of this catalyst was trackedvia13C NMR. Results support Re5-PAN (φ= 0.021) functioning as a catalyst for the reduction of CO2(maximum turn-over 48-50 at 300 equiv. triethylamine as the sacrificial electron donor).
