本文以手性碳纳米管为模板,成功地在其内部形成了手性银纳米线.由于手性排列的银纳米线之间的集合耦合效应,在可见光区和近红外区产生了较强的手性圆二色信号.根据我们先前报道的方法,通过碳化处理自组装合成的手性吡咯碳纳米管得到了单一手性的碳纳米管.由于毛细管效应,银离子能够很容易地进入手性碳纳米管的手性孔道中,然后再通过氢气高温还原,在其管内得到了具有光学活性的手性银纳米线.手性碳纳米管内的螺旋孔道对手性银纳米线的形成起模板作用.该合成体系将有助于理解具有手性光学活性的无机材料的形成及其机理.这种新颖的手性无机材料也将有机会应用到非线性光学器件、生物传感和手性识别等领域.
In this paper, chiral CNTs were successfully used as templates to form chiral silver nanowires in their interior. Due to the collective coupling effect between chiral aligned silver nanowires, a strong Chiral circular dichroism signals. According to our previously reported method, single-chiral carbon nanotubes were obtained by self-assembly of the synthesized chiral pyrrole carbon nanotubes by carbonization. Due to the capillary effect, silver ions can easily enter the chiral The chiral nanotubes in chiral nanotubes were chirally charged with hydrogen, and then the optically active chiral silver nanowires were obtained in their tubes. The spiral channels in the chiral nanotubes played a template role in the formation of chiral silver nanowires. The synthesis system will help to understand the formation and mechanism of inorganic materials with chiral optical activity, and the novel chiral inorganic materials will also have the opportunity to be applied to fields such as nonlinear optical devices, biosensing and chiral recognition .
