Abstract
Organic semiconductors have broad applications in devices such as sensors, photovoltaic cells, and light-emitting diodes. Compared to inorganic semiconductors, organic semiconductors have better performance on both weight and cost. Using ipso-arylative coupling reactions to prepare semiconducting conjugated polymers allows the use of stable monomers and avoids toxic by-products generated during polymerization. Poly(3-hexylthiophene), P3HT, is used broadly as a semiconducting layer in organic thin-film field effect transistor (FETs) and solar cells. Here, we report the effectiveness of microwave irradiation to accelerate the rate of P3HT synthesis by ipso-arylative coupling. The effects of reaction parameters, such as temperature, concentration, reaction time and ratio of catalyst are reported. The molecular weights were measured by gel permeation chromatography(GPC) and the structure were confirmed by proton nuclear magnetic resonance (1H NMR). | 36 pages
