Different Chiral Selective Recognition/Extraction of (n,m)Single-walled Carbon Nanotubes Using Copolymers Carrying a Carbazole or Fluorene Moiety

We describe the finding that copolymers having a long-double chain carbazole or fluorene group connected to benzothiadiazole with thiophene linkers show a different chiral selective (n,m)single-walled carbon nanotube (SWNT) solubilization behavior which was revealed by 2D photoluminescence and vis near IR spectroscopies. We also carried out molecular mechanical simulations to understand the difference in the chiral selective solubilization behavior.
