Query: Thioethyl-porphyrazine/Nanocarbon Hybrids for Photoinduced Electron
  Transfer   We designed a novel pyrene-substituted thioethyl-porphyrazine (PzPy) and the
formation of supramolecular assembly with nanocarbons demonstrating
photoinduced electron transfer ability. As revealed by spectroscopic and
electrochemical studies, PzPy displays wide spectral absorption in the visible
range, charge separation upon photoexcitation, as well as bandgap and highest
occupied/lowest unoccupied molecular orbital (HOMO/LUMO) energy values,
matching the key requirements of organic optoelectronic. Moreover, the presence
of a pyrene moiety promotes attractive interactions with pi-conjugated systems.
In particular, theoretical calculations show that in the PzPy the HOMO and LUMO
are localized on different positions of the molecule, i.e., the HOMO on the
pyrene moiety and the LUMO on the macrocycle. Therefore, HOMO-LUMO excitation
gives rise to a charge separation, preventing excitons recombination. Two kinds
of non-covalent hybrid composites are prepared by mixing the PzPy with single
wall carbon nanotubes (SWNTs) and graphene nanoflakes (GNFs), respectively, and
used for photocurrent generation through charge transfer processes between PzPy
and nanocarbons. Photoconduction experiments show photocurrent generation upon
visible light irradiation of both PzPy/SWNT and PzPy/GNF composites (0.78 and
0.71 mA/W at 500 nm, respectively), demonstrating their suitability for
optoelectronic applications and light harvesting systems.
