Material issues for construction of organic and polymeric driving circuits for display and electronic applications

摘要

Organic and polymeric driving circuits may be a possible alternative to realize low cost flexible and large area flat panel displays. Recent efforts have been directed to the discovery of solution processable polymeric semiconductors for the ease of fabrication and low cost. In this paper, we report the investigation of various 3-substituted regioregular polythiophenes as active semiconductors for field-effect transistors. The best transistor performance has been found with regioregular poly(3-heaxylthiophene). The difference in their device performance was correlated to the structure and morphological behavior of these regioregular polythiophenes. [References: 11]
