摘要：

The complex [{Ru(bipy)(2)}(3)(mu(3)-L)](3+) (H6L = hexahydroxy-triphenylene), in which the tris-dioxolene bridging ligand is formally in the tris-semiquinone oxidation state [sq,sq,sq], undergoes three reversible ligand-centred oxidations to the [q,q,q] state (q = quinone); it exhibits very strong NIR absorption arising from Ru --> L charge transfer whose maximum wavelength may be tuned over a wide range according to oxidation state.
