Abstract: Si-Cu alloys have been prepared by electroless depositions with different process. Si-Cu/MCMB materials have been prepared by carbonization of the mixture of Si-Cu, MCMB and mesophase pitch. The influences of electroless deposition condition and heat-treatment temperature on the anodic performance of Cu-Si/MCMB have been studied. Compared with Si/MCMB, Si-Cu/MCMB has more stable cyclical performance. Furthermore, the Si-Cu/MCMB sample produced by cleaning and then electroless deposition on Si shows the better anodic performance than the Si-Cu/MCMB sample produced by direct electroless deposition on Si, because the former sample has more Cu contents than the latter sample.

Abstract: A novel polyfluorene derivative, poly[(9,9-bis(3'-(N,N-dimethylamino)propyl)-2,7- fluorene)-alt-2,7-(9,9- p-divinylbenzene)] (P-1) was synthesized by the palladium-catalyzed Suzuki coupling reaction and it’s quaternized ammonium polyelectrolyte derivatives was obtained through a postpolymerization treatment on the terminal amino groups. The electrochemical and optical properties of the resulting copolymers was fully investigated. The results showed that the new polyfluorene derivative had potential useful in used as materials for electronic conductivity, chemical and biological sensors that derive from its highly conductive and strong fluorescence.
