Ordered assembly of protonated porphyrin driven by single-wall carbon nanotubes. J- and H-aggregates to nanorods

Ordered assemblies of protonated porphyrin in the form of J- and H-type aggregates have been achieved on the single-wall carbon nanotube (SWCNTs) surface. This unusual molecular aggregation phenomenon driven by SWCNTs further enables macroscopic assembly in the form of linear bundles.
