A simple, single-column, high-throughput fractionation procedure based on size-exclusion chromatography of aqueous sodium dodecyl sulfate suspensions of single-walled carbon nanotubes (SWCNTs) is presented. This procedure is found to yield monochiral or near monochiral SWCNT fractions of semiconducting SWCNTs. Unsorted and resulting monochiral suspensions are characterized using optical absorption and photoluminescence spectroscopy.
提出了一种简单、单柱、高通量的单壁碳纳米管(SWCNT)在水溶液中十二烷基硫酸钠(SDS)悬浮液的尺寸排阻色谱分离方法。该方法可得到单分散或近单分散半导体 SWCNT 的手性 SWCNT 级分。未分级和得到的单分散悬浮液采用光学吸收和光致发光光谱进行表征。
