Liquid-Crystalline Electronic Polymers for Transistors

Significance

Organic semiconductive polymers promise to revolutionalize the production of low-cost electronics if materials with sufficient performance can be produced. A critical element of any logic circuit is the transistor, and the generating materials that assemble spontaneously into structures with high performance are an important goal. This contribution reports an electronic polymer that can be processed in a liquid-crystalline state and displays high carrier mobility that enables transistors to function at higher speeds. The performance of this system exceeds previous polymer systems and rivals the best small-molecule crystalline devices.
