Shorter Alkyl Chains Enhance Molecular Diffusion and Electron Transfer Kinetics between Photosensitisers and Catalysts in CO₂ -Reducing Photocatalytic Liposomes.

Strikingly, a clear trend was observed: the photochemical performances of the photocatalytic liposomes were inversely correlated to the alkyl chain length, with the turnover number (TON=n product /n Re‐catalyst ) and photocatalytic turnover number (PTON=2 × n product /n Ru‐photosensitiser ; the factor 2 accounts for the fact that 2 molecules of photosensitiser must turnover once for the formation of one CO molecule) decreasing regularly from the C 9 to the C 19 system (Figure 2 , Table S5, and S6, which give both η immob ‐corrected and uncorrected TON and PTON, see below).
