title: Anchoring of phosphorus-containing cobaltabisdicarbollide derivatives to titania surface.
abstract: Cobaltabisdicarbollide derivatives have been anchored for the first time to the surface of TiO(2) particles using two phosphorus-containing cobaltabisdicarbollide derivatives: Cs[1,1'-mu-(HO)(O)P-3,3'-Co(1,2-C(2)B(9)H(10))(2)], Cs[1], and Cs[8,8'-mu-(OH)(O)-P(O)(2)-3,3'-Co(1,2-C(2)B(9)H(10))(2)], Cs[2]. Grafting of cobaltabisdicarbollide anions to the TiO(2) particle surface through phosphinate or phosphate anchors has been achieved by using standard conditions. Characterization of the modified titanium dioxide surfaces by FTIR, (11)B and (31)P NMR, DRUV-vis spectroscopy, and transmission electron microscopy (TEM) indicates an efficient functionalization on the particle surface.
