摘要：Hyperbranched poly(diethynylbenzene-silane) (hb-PDEBS) was synthesized through polycondensation reaction of diethynylbenzene Grignard reagent (A2) and trichlorosilane (B3), and its structure was characterized by FT-IR, 1H-NMR, GPC and Elemental Analysis. The degree of branching of hb-PDEBS was defined by 29Si-NMR and calculated to be about 0.68. The curing behavior of hb-PDEBS was investigated by DSC. Thermal stability of cured hb-PDEBS was examined by TGA, and its residue at 1000°C under nitrogen was 80.6%. Hb-PDEBS displayed a strong absorption due to π-π* transition and exhibited the most intensity structured emission with a maximum around 500 nm. ? (2012) Trans Tech Publications, Switzerland.
