Unusual partner radical trimer formation in a host complex of cucurbit[8]uril, ruthenium(II) tris-bipyridine linked phenol and methyl viologen.
A stable 1:1:1 inclusion complex of Ru(bpy)(3)-phenol (1), MV(2+) and cucurbit[8]uril (CB[8]) is formed in aqueous solution. In the presence of triethanolamine (TEOA), a light-induced formation of unusual partner radical trimer 1-(MV(+*))(2)-CB[8] has been observed for the first time.
