AB A cucurbit[8]uril (CB[8])-secured platinum terpyridyl chloride dimer was used as a photosensitizer and hydrogen-evolving catalyst for the photoreduction of water. Volumes of produced hydrogen were up to 25 and 6 times larger than those obtained with the corresponding free and cucurbit[7]uril-bound platinum monomer, respectively, at equal Pt concentration. The thermodynamics of the proton-coupled electron transfer from the Pt(II)–Pt(II) dimer to the corresponding Pt(II)–Pt(III)–H hydride key intermediate, as quantified by density functional theory, suggest that CB[8] secures the Pt(II)–Pt(II) dimer in a particularly reactive conformation that promotes hydrogen formation.
