Abstract
This research involved the synthesis of poly(3-hexylthiophene) and poly(3-octylthiophene) via oxidative condensation with the presence of anhydrous ferric chloride as the catalyst. Polymers obtained were characterized by using FTIR, NMR and UV-Visible absorption spectroscopy, TGA and DSC. Poly(3-hexylthiophene) and poly(3-octylthiophene) were successfully synthesized with number average molecular weights of 6,600 and 20,700 g/mol respectively as measured by gel permeation chromatography. The potential of poly(3-alkylthiophene) solutions as sensing agent for the detection of oxygen gas was studied. Solvents used were chloroform, tetrahydrofuran and toluene. UV-Visible absorption spectrum of polymer solutions were recorded before and after the polymer solutions were purged with oxygen gas to study the response of polymer solutions towards oxygen gas. Results obtained showed that all polymer solutions were responsive to the presence of oxygen gas with poly(3-hexylthiophene) solution in chloroform was found to be the best.
