Purification and isolation of SWNTs

This work involves the purification and isolation of arc-discharge and HiPco SWNTs using two different systems. The first involves the use of conjugated polymers such as PmPV to selectively isolate certain tubes. The second uses SWNT as templates for organic molecules such as terphenyl and anthracene. Improvements in the solubility of SWNTs are seen in both cases. Spectroscopic analyses indicate a specific interaction between the tubes and the organic species. (C) 2003 Elsevier Ltd.
