Resumen:
In-situ synthesis by Grignard Metathesis and properties of a
nanocomposite of poly (3-hexylthiophene) (P3HT) with Cadmium Sulfide
(CdS) nanoparticles (P3HT/CdS) are reported. This synthesis method was
used to obtain higher HT configuration in the P3HT/CdS nanocomposites
synthesized in-situ, in order to improve their properties. It is
noteworthy that this method has not been used for in-situ synthesis of
such nanocomposites. P3HT synthesis was carried out in presence of
different CdS content (3HT/CdS weight ratio of 1/0.01, 1/0.05 and
1/0.11). Regioregular P3HT (RR-P3HT) and P3HT/CdS composites were
characterized by FTIR, H-1 NMR, UV-Vis, photoluminescence,
photoresponse, TGA, XRD and SEM-EDX. Effects of CdS content on
properties in P3HT/CdS nanocomposites were studied. The formation of
P3HT/CdS nanocomposites was confirmed by the FTIR spectra, CdS low
concentration in P3HT led to better interaction between CdS and P3HT. A
greater regioregularity to 94% in P3HT within the composite was
obtained. The composites exhibited interesting optical and electrical
properties for optoelectronic devices.
