Supramolecular interactions of conjugated Zn- and protonated porphyrin polymer with carbon nanotubes

The interaction of a highly soluble conjugated Zn -porphyrin containing polymer with a surface of single-walled carbon nanotubes, producing a soluble polymer-nanotube complex, is reported. We found that successful complexation required the addition of trifluoroacetic acid to the solvent tetrahydrofuran in order to disrupt solvent-porphyrin coordination that prohibits close interaction of the polymer with the nanotube surface. In the presence of …
