In this study, we investigated the effect of the ligand structure of zeolitic imidazolate structures (ZIFs) on the CO₂-responsive properties of composites of single-walled carbon nanotubes (SWCNTs). By evaluating the crystal size and morphology of these composite films and measuring the resistance change upon CO₂ adsorption, we investigated the effect of the electrical properties of the ligands on the charge transfer.
