中文摘要：
设计合成了带巯基的聚苯乙炔衍生物,在产物的红外光谱上,3312和776 cm^-1处炔氢特征吸收与2106 cm^-1处碳碳三键的特征红外吸收消失;在产物的1H-NMR谱上,对应单体上炔氢的化学位移（δ=3.0）消失而对应共轭烯烃的化学位移（δ=6.4）出现;这些谱学特征变化证明了聚合反应的发生.巯基官能化的聚苯乙炔不仅能够发挥聚苯乙炔衍生物对碳纳米管的增溶作用,而且具有将碳纳米管表面巯基功能化的特殊性能.通过巯基与ZnO之间的强相互作用,ZnO纳米粒子被组装到巯基官能化的聚苯乙炔/碳纳米管杂化结构的外壳.本研究提供了制备新的多元复合纳米结构材料的方法.
英文摘要：
A thiol-functionalized poly（phenylacetylene） has been synthesized and characterized. The disappearance of the characteristic vibrations at 3312 and 776 cm^-1 （C=C-H） and 2106 cm^-1 （C=C）, together with the vanishing of the chemical shifts at 3.0 （C=C-H） and the appearance of the chemical shifts at 6.4 （C=C-H） indicate the polymerization of the thiol-containing monomer. The hybrid of thiol-functionalized poly- （phenylacetylene） and multiwalled carbon nanotubes （MWNTs） showed good solubility in organic solvents. Meanwhile, the wrapping of the polymer chains on MWNTs led to the surface functionalization. By aid of the interactions between thiol groups and zinc cations, ZnO nanoparticles were assembled onto out-shells of the hybrids. These results suggested a novel route to the fabrication of multi-component nanostructures.
