===Abstract===
====Summary====
A photochemical reduction of CO<sub>2</sub> to CO was shown using the zinc porphyrin dyad with a connected rhenium complex {{#moleculelink:|link=LYVLANYMDXKDOV-CVVGJFHCSA-M|image=false|width=300|height=200}} as a combined catalyst and photosensitizer molecule. Turnover numbers (TONs) of >1300 and a selectivity of >99.9% for CO were reached in DMA. The experiments were conducted under visible-light irradiation (λ = 420 nm) using BIH as sacrificial electron donor (see section SEDs below).
====Advances and special progress====
A selective method for the reduction of CO<sub>2</sub> to CO with a porphyrin-rhenium complex dyad was presented, effectively linking the catalyst and photosensitizer in one molecule.

====Additional remarks====
===Content of the published article in detail===
The article contains results for the reduction of CO<sub>2</sub> to CO under visible-light catalysis using {{#moleculelink:|link=LYVLANYMDXKDOV-CVVGJFHCSA-M|image=false|width=300|height=200}} as a catalyst and photosensitizer. The catalytic system performs best (referring to the TON of CO production) in DMA.
