We used the thiophene unit for enhanced refractive index due to their specific characters. In this research, the thiophene-containing polystyrene was synthesized according to two step reaction. The copolystyrenes were polymerized by general radical polymerization with controlled mole ratios 0:10, 1:9, 3:7, 5:5, 7:3, 9:1, 10:0 (Styrene: p-bromostyrene), respectively. After then, the thiophene-containing polystyrenes were synthesized by Suzuki-Miyaura coupling reaction. The chemical structures of synthesized thiophene-containing polystyrene in accordance with ratios were confirmed by using 1H-NMR, 13C-NMR, and FT-IR. The effect of the thiophene units on refractive index according to copolymer ratios were confirmed by using prism coupler. The thiophene-containing polystyrene showed improved refractive index ranging from 1.58 to 1.67 and birefringence in the range of 0.0001~0.0019. |
