Chemiresistive detectors for amine vapors were made from single‐walled carbon nanotubes by noncovalent modification with cobalt meso‐arylporphyrin complexes. We show that through changes in the oxidation state of the metal, the electron‐withdrawing character of the porphyrinato ligand, and the count...
