Characterisation of cobalt(II)porphyrin/carbon nanotube nanohybrids by electron paramagnetic resonance

We study multi-component EPR spectra of cobalt(II)porphyrin/SWNT nanohybrids. Their g-anisotropy, hyperfine interaction and g- and hyperfine strains are monitored under different treatments. Our results affirm the electron acceptor behaviour of the SWNTs in these nanohybrids, in agreement with DFT calculations.[3] In the EPR spectra we can distinguish porphyrins interacting with metallic and semiconducting SWNTS.
