Polythiophenes became more attractive in diverse applications due to some of their inherent properties including thermal and environmental stability as well
as optical and electronic conductive properties. Commonly thiophene monomers are obtained from byproducts of crude oils. The current study discuss for
the first time the synthesis and characterization of light harvesting polythiophenes copolymers from thiophene derivatives extracted from \textit{Tagetes}
species. There were mainly two thiophenes derivatives, 5-(3-buten-1-ynyl)-2,2-bithienyl and 2 ,2 ', 5 , 2"-terthienyl (terthiophene), in the roots of the plant.
Chemical oxidative radical polymerization was followed during the synthesis of copolymers with various block compositions of plant based terthiophenes and
3-hexyl terthiophenes. Structural characterization of the synthetic products was done using FTIR, NMR, Uv-vis, XRD and DSC techniques. Polythiophene
homopolymers obtained from plant based terthiophenes have limited processability of solar cells due to poor solubility in common organic solvents. A
significant solubility improvement was observed with copolymers having minor contributions of 3-hexylthiophenes. |
