Silylene-Spaced Copolymers Containing Alternating Three-Block Divinyl Arylene Groups: Synthesis and Photophysics
碩士 === 國立臺灣大學 === 高分子科學與工程學研究所 === 94 === A series of silylene-spaced copolymers containing alternating aryl groups [(donor)n-SiMe2-(acceptor-1)m-SiMe2-(acceptor-2)-SiMe2] were synthesized by rhodium-catalyzed hydrosilylation of bis-alkynes with bis-silylhydrides. Bis-silylhydrides were prepared b...

Bis-silylhydrides were prepared by nickel-catalyzed olefination of the corresponding aryl bisdithioacetals with Grignard reagent (Me2(iPrO)SiCH2MgCl) followed by LiAlH4 reduction. Bis-alkynes were obtained by Sonogashira reaction. This strategy provided a powerful arsenal to construct a regioselective polymeric backbone containing several chromophores with desired ratios of donors and acceptors. In these three-chromophore system, biphenyl was used as an energy donor; stilbene as the first acceptor and terphenylenedivinylene as the second acceptor. The silylene group was an insulating spacer as well as a linker among chromophores. The photophysical properties were also examined in details. Tien-Yau Luh 陸天堯 學位論文 ; thesis 73 zh-TW |
