Thiophene pyrenyl derivatives for the supramolecular processability of single-walled carbon nanotubes in thin film heterojunction
A major problem for the use of single-wall carbon nanotubes (SWCNTs) in
electronic devices relates to their poor processability. Chemical
modification inevitably introduces defects in the nanotube lattice,
resulting in a loss of electronic properties. In this contest, we report
on a supramolecular approach with the aim of increasing the dispersion
of SWCNTs in solution and in organic semiconductor matrices by ensuring
the optoelectronic properties. In particular, new pyrenyl derivatives of
thiophene have been synthesized and used to improve the solubility of
SWCNTs for electron transfer in thin film heterojunction with
poly(3-hexylthiophene) (P3HT) as donor system. Photoinduced electron
transfer to SWCNTs has been demonstrated and the effect of different
alkyl spacers, between the pyrene unit and the thiophene moiety, has
revealed to play a key role. Electron transfer has been maximized by the
compound with a spacer coplanar with the pyrene moiety due to the
reduced separation between P3HT and SWCNTs.
