AbstractHighly porous organic structures are synthesized by the oxidative polymerization of pyrrole derivatives in a concentrated monomer and oxidant solution. The rapid polymerization of pyrrole by oxidation with FeCl3 in CHCl3 as a cosolvent for the monomer and the oxidant leads to nanometer-scale branching morphologies that have a specific surface area of ~200 m2 g−1. The polymerization of pyrrole derivatives, such as 1-methylpyrrole and 1-ethylpyrrole, produced intragranular micropores of ~1 nm in diameter in the polymer grains of nanoscale dendrites. We obtained highly porous polymers of polypyrrole derivatives that have high specific surface areas (~900 m2 g−1) with bimodal pore-size distribution. The enhanced adsorbability of porous polymer dendrites for aromatic molecules was confirmed, in comparison with that of conventional polystyrene adsorbents.Highly porous organic structures are synthesized by the oxidative polymerization of pyrrole derivatives in a concentrated monomer and oxidant solution.

通过快速氧化聚合合成的吡咯衍生物的高多孔聚合物枝晶

摘要 通过吡咯衍生物在浓缩单体和氧化剂溶液中的氧化聚合合成了高度多孔的有机结构。吡咯通过在 CHCl3 中用 FeCl3 作为单体和氧化剂的共溶剂氧化而快速聚合,导致纳米级支化形态,其比表面积约为 200 m2 g-1。吡咯衍生物(如 1-甲基吡咯和 1-乙基吡咯)的聚合在纳米级枝晶的聚合物颗粒中产生直径约 1 nm 的颗粒内微孔。我们获得了具有高比表面积 (~900 m2 g-1) 和双峰孔径分布的聚吡咯衍生物的高多孔聚合物。证实了多孔聚合物枝晶对芳族分子的吸附能力增强,与传统的聚苯乙烯吸附剂相比。高度多孔的有机结构是通过吡咯衍生物在浓缩单体和氧化剂溶液中的氧化聚合合成的。通过在 CHCl3 中用 FeCl3 作为单体和氧化剂的共溶剂氧化,吡咯衍生物的快速聚合导致纳米级支化形态,其比表面积约为 900 m2 g-1,具有双峰孔径分布。
