Nanoscience and technology is an emerging field for scientists and engineers due to remarkable mechanical and electronic properties properties of carbon nanotubes (CNTs), and their application in designing optoelectronic and photovoltaic devices. In this report, single wall carbon nanotubes (SWCNTs) are solubilized via non-covalent, π− π stacking with pyrene-functionalized with phenyl imidazole co-ordinating ligand and selfassembled donor-acceptor nanohybrids were formed with electron donors, Zinc porphyrin (ZnP) or Zinc napthalocyanine (ZnNC). The nanohybrids are fully characterized by TEM, UV-Vis, NIR, and electrochemical studies. Efficient electron transfer from the donor ZnP and ZnNC entities to the acceptor SWCNTs and generation of the photo-excited state is revealed by steady-state and time resolved emission studies respectively
