Charge transfer distance between tris(2,2′-bipyridine) ruthenium(II) redox centers incorporated in Nafion® membrane

The complexes FcNHC (O)CCo3(CO)9 ( Fc = ferrocenyl ) (3) and Fc ( alaOMe )C(O)CCo3(CO)9 (ala = alanine ) (5) have been synthesized from the +C(O)CCo3(CO)9 cation and FcNH2 or Fc ( alaOMe )H respectively. Derivatives FcNHC (O)CCo3(CO)6[P( OPh )3]3 (4) and Fc ( alaOMe )C(O)CCo3(CO)6[P( OPh )3]3 (6) are also described. Analysis of the spectroscopic and redox behaviour shows that the amide linkage acts as a -I, -M substituent group to Fc and the Co3C unit acts as a-I, +M group. Unlike complexes where these redox centres are directly linked, electronic effects are not transmitted between Co3C and Fc . Oxidation at the ferrocene centre and reduction at the Co3C centre in (3) and (5) is chemically reversible whereas oxidation of the amino acid moiety is irreversible; oxidation of the cluster takes place in (4) and (6) but no intervalence charge transfer is observed.

The porous spherical architecture of TaON plays a significant role in photoreduction of CO2, including the more reaction sites, easier trapping of photon, and shorter charge transfer distance from interior to surface to expedite charge separation.
