Two new silylene-spaced copolymers containing three kinds of different chromophores in regioregular manner were synthesized by rhodium-catalyzed hydrosilylation of a bisalkyne with a bis-silyl hydride. The photophysical and electrochemical properties of these polymers and the corresponding monomeric models were investigated. Time-resolved fluorescence spectroscopy has been employed for detailed kinetic analyses. The chromophores in these polymers have been shown to exhibit light harvesting to collect light energy, energy transfer, and efficient charge separation. The overall efficiencies involving both FRET and PET in these silylenespaced vinylarene copolymers can be up to 96%. © 2008 American Chemical Society.
