Abstract
The effects of the highly fluorescent 4-piperidinyl-1,8-naphthalimide (PNI) chromophore on the CO2 reduction catalytic properties of rhenium-based catalysts are investigated herein. In particular, the electro- and photocatalytic CO2 reduction features of [Re(CO)(3)(bpy)Cl] (bpy = 2,2-bipyridine) are compared with the activity of [Re(CO)(3)(phen-PNI)Cl] (phen = 1,10-phenanthroline), which is known for its long excited-state lifetime. Moreover, another Re complex, namely [Re(CO)(3)(bpy-Ph-PNI)Cl], has been synthesized and tested as an electro- and photocatalyst. The catalytic properties of the selected compounds were studied by means of electrochemical (cyclic voltammetry and controlled-potential electrolysis) and photophysical measurements together with DFT calculations. [Re(CO)(3)(bpy-Ph-PNI)Cl] showed good electrocatalytic efficiency toward selective CO2 reduction to CO, as well as reduced electrocatalytic overpotential.Pubblicazioni consigliate
