We have been developing the methodology to discriminate the handedness and diameter of single-walled carbon nanotubes (SWNTs) through molecular recognition using chiral diporphyrin nanotweezers. Although relatively small diameters of SWNTs (less than 1.0 nm) were recognized well, nanotweezers were not able to form stable complexes with the SWNTs with the diameters larger than 1.0 nm. In this context, we designed chiral diporphyrin with much larger cavity; namely "nanocalipers". As expected, we obtained optically active SWNTs with more than 1.0 nm in diameter and, unexpectedly, enriched metallic SWNTs over semiconducting ones. The optically active metallic SWNTs are identified for the first time, in addition to the optically active semiconducting SWNTs with such large diameters. Higher selectivity to metallic SWNTs are observed in the case of pyrene-based nanocalipers.

我们一直在开发通过使用手性二磷林纳米透明剂的分子识别来区分单壁碳纳米管（SWNT）的惯性和直径的方法。尽管很好地识别了SWNT的直径相对较小的直径（小于1.0 nm），但纳米wee剂无法与直径大于1.0 nm的SWNT形成稳定的复合物。在这种情况下，我们设计了具有较大腔的手性二脑蛋白。即“纳米级别”。如预期的那样，我们获得了直径超过1.0 nm的光学活性SWNT，并且在半导体上出乎意料地富集了金属SWNT。除了具有如此大的直径的光学活跃的半导体SWNT之外，还首次确定了光学活跃的金属SWNT。在基于pyrene的纳米含量的情况下，观察到对金属SWNT的更高选择性。
