π-Conjugated Organic Semiconductors for Field-Effect Transistors

Organic semiconductors employed as active layers in field-effect transistors （FETs） are of great current interest because such FETs can potentially be fabricated at low cost, over large areas, and on flexible substrates. Such facile fabrication approaches offer a significant advantage over silicon technology in numerous applications. Much progress about organic FETs has been made in various organic-based electronic circuits, such as displays, sensor, inverts and logic elements. Of all the OFET materials reported so far,
