Abstract

Strategies for single-walled carbon nanotube (SWNT) separation are critical to developing nanotubes as useful nanoscale building blocks. Herein, we demonstrate that solution-phase ozonolysis of SWNTs fosters diameter selectivity in SWNTs. The main conclusion of our work is that in this sidewall addition reaction, smaller diameter tubes react more extensively than larger diameter tubes, which provides experimental validation for theoretical predictions on the role of pyramidalization and π-orbital misalignment in nanotube reactivity.
