Heteroternary cucurbit[8]uril complexes as supramolecular scaffolds for self-assembled bifunctional photoredoxcatalysts

The self-assembly of bifunctional photoredoxcatalysts is reported. A series of photosensitizers and water-reducing catalysts were functionalized with viologen- and naphthol-units, respectively. Subsequent formation of the heteroternary cucurbit[8]uril-viologen-naphthol complexes was used for the constitution of bifunctional photoredoxcatalysts for hydrogen generation.

Automated summary

This study reports the self-assembly of bifunctional photoredoxcatalysts by functionalizing a series of photosensitizers and water-reducing catalysts with viologen- and naphthol-units, followed by the formation of heteroternary cucurbit[8]uril-viologen-naphthol complexes for hydrogen generation.
