Abstract: Alternating regioregular silylene-spaced divinylarene copolymers [(donor-SiMe2-)n=1-3-(acceptor-SiMe2)] are synthesized by rhodium-catalyzed hydrosilylation of bis-alkynes with bisvinylic silyl hydrides. Efficient intrachain energy transfer has been observed in these copolymers. The intensities of emission profiles depend on the relative ratio of donor-to-acceptor chromophores. The corresponding inorganic/organic hybrid materials are synthesized, and their photophysical properties are described.
