A new type of “smart” single‐walled carbon nanotubes is created by wrapping a pyrene‐labeled CO 2 ‐responsive polymer via π–π stacking. The polymer/SWNT hybrids not only undergo a hydrophobic–hydrophilic transition upon CO 2 stimulus of CO 2 in a mixed solvent, but also exhibit switchable dispersion/aggregation states upon the alternate bubbling of CO 2 and N 2 in pure water.
