用铑催化双炔与双乙烯基硅氢化物的硅氢化反应合成了交替区域规则的硅炔间距二乙烯芳烃共聚物[（给体- sime2 -）(n=1-3)-（受体- sime2）]。这些共聚物具有高效的链内能量传递。发射谱线的强度取决于供体与受体发色团的相对比例。合成了相应的无机/有机杂化材料，并描述了其光物理性质。
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 of served in these copolymers. The intensities of emission profiles depend oil the relative ratio of donor-to-acceptor chromophores. The corresponding inorganic/organic hybrid materials are synthesized, and their photophysical properties are described.
