  Removable and Recyclable Conjugated Polymers for Highly Selective and High-Yield Dispersion and Release of Low-Cost Carbon Nanotubes

  摘要：

  High-purity semiconducting single-walled carbon nanotubes (s-SWNTs) with little contamination are desired for high-performance electronic devices. Although conjugated polymer wrapping has been demonstrated as a powerful and scalable strategy for enriching s-SWNTs, this approach suffers from significant contaminations by polymer residues and high cost of conjugated polymers. Here, we present a simple but general approach using removable and recoverable conjugated polymers for separating s-SWNTs with little polymer contamination. A conjugated polymer with imine linkages was synthesized to demonstrate this concept. Moreover, the SWNTs used are without prepurifications and very low cost. The polymer exhibits strong dispersion for large-diameter s-SWNTs with high yield (23.7%) and high selectivity (99.7%). After s-SWNT separation, the polymer can be depolymerized into monomers and be cleanly removed under mild acidic conditions, yielding polymer-free s-SWNTs. The monomers can be almost quantitatively recovered to resynthesize polymer. This approach enables isolation of clean s-SWNTs and, at the same time, greatly lowers costs for SWNT separation.

• Phosphorescence from a pure organic fluorene derivative in solution at room temperature
  作者：Jinjia Xu、Atsuro Takai、Yuka Kobayashi、Masayuki Takeuchi

  DOI：10.1039/c3cc44809f

  日期：——

  A fluorene derivative having both bromo and formyl groups exhibited bright phosphorescence emission in common organic solvents at room temperature. The absolute phosphorescence quantum yield reached 5.9% in chloroform at 298 K. When the fluorene derivative was incorporated into a poly(methyl methacrylate) film, the phosphorescence emission was similarly observed even under air at room temperature for over five days.

  一种同时具有溴基和甲酰基的芴衍生物在室温下的普通有机溶剂中表现出明亮的磷光发射。在 298 K 的氯仿中，绝对磷光量子产率达到 5.9%。当把这种芴衍生物加入聚甲基丙烯酸甲酯薄膜中时，即使在室温空气中也能观察到类似的磷光发射，持续时间超过五天。
