Abstract
The polymerization of 2-ethynyl-5-hexylthiophene (2E5HT), 2-hexyl-5-((perfluorophenyl)ethynyl)thiophene (HT≡FPh), 2-hexyl-5-(3,3,3-trifluoroprop-1-yn-1-yl)thiophene (HT≡CF3), 1-ethynyl-2,3,5,6-tetrafluoro-4-methoxybenzene (1ETFMB), 1-ethynyl-2,3,5,6-tetrafluoro-4-(trifluoromethyl)benzene (PFPA), and ethynylbenzene with transition metal catalysts (tantalum (V) chloride, molybdenum (VI) tetrachloride oxide, and 2nd Generation Grubbs Catalyst) was investigated. The targeted polymers and copolymers were designed to have both electron-donating and electron-withdrawing groups conjugated to the polyacetylene backbone to tune the electronic and optical properties for potential application in organic photovoltaic solar cells. The optical properties of the resulting oligomers and polymers were analyzed by UV-Vis absorption spectroscopy. | The polymerization of 2-ethynyl-5-hexylthiophene (2E5HT), 2-hexyl-5-((perfluorophenyl)ethynyl)thiophene (HT≡FPh), 2-hexyl-5-(3,3,3-trifluoroprop-1-yn-1-yl)thiophene (HT≡CF3), 1-ethynyl-2,3,5,6-tetrafluoro-4-methoxybenzene (1ETFMB), 1-ethynyl-2,3,5,6-tetrafluoro-4-(trifluoromethyl)benzene (PFPA), and ethynylbenzene with transition metal catalysts (tantalum (V) chloride, molybdenum (VI) tetrachloride oxide, and 2nd Generation Grubbs Catalyst) was investigated.
