Fullerene-porphyrin supramolecular nanocables

Novel fullerene-porphyrin supramolecular nanocables were designed and their electronic properties were studied using computational modeling and first-principles density functional theory. It is demonstrated that two well-defined fullerene-porphyrin nanocables have clear channels for charge transport by electrons and holes. These two interesting nanocables have zigzag or helical chains of ##IMG## [http://ift.tt/1kpbPKT] {${{{\rm{C}}}_{60}}$} molecules around a π -stacked porphyrin core. They also have frontier electronic states which are spatially extended along the axes of the nanocables. Ballistic electronic transport is possible for ultrafast transfer of electrons along ##IMG## [http://ift.tt/1lQCVcd] {${{{\rm{C}}}_{60}}$} chains. We believe these supramolecular nanocables can play important roles in molecular electronics, optoelectronics...
