Synthesis of poly[9-methyl-9-[8-(thioacetate)-octyl]-fluorene] and its gold nanocomposite

合成了一种新型的侧链含硫代乙酸辛酯基的聚芴衍生物,聚[9-甲基-9-(8-硫代乙酸辛酯基)-芴](PFMOTA)。用这种聚合物修饰金纳米粒子,得到了稳定的PFMOTA/金纳米粒子复合物。采用TEM、GPC、FTIR、UV-vis和PL光谱对聚合物及其修饰的金纳米粒子复合物的结构和性能进行了表征。

Poly[-9-methyl-9-[-8-（thioacetate）-octyl]-fluorene] （PFMOTA）,a new electroactive polyfluorene derivative with 8-（thioacetate）-octyl in the side chain,has been synthesized in the presence of FeCl3 as the oxidizing reagent. Imposing the PFMOTA to stabilize gold nanoparticles,thus obtained gold nanoparticles modified with PFMOTA are stable under ambient condition, which is attributed to the protection of the PFMOTA densely packed on the gold surface. TEM, GPC, IR, UV-Vis and PL spectra have been employed to investigate the structure and performance of the polymer and the gold nanoparticles.
