A novel fulleropyrrolidine covalently linked to a tris(2,2′‐bipyridine)ruthenium( II ) complex is presented (see picture). While electrochemical investigations suggest the absence of any ground‐state interaction between ruthenium and fullerene chromophores, photoinduced optical absorption studies clearly show that electron transfer occurs to afford the Ru 3+ −C 60 . −pair with characteristic fullerene radical anion band at λ max = 1040 nm.
