Organic Field-Effect Transistors liquid

As a class of n-type organic semiconductors, PBI derivatives have received considerable attention for a variety of applications [312, 313], for example, for organic or polymer light-emitting diodes (OLEDs and PLEDs) [314, 315], thin-film organic field-effect transistors (OFETs) [316, 317], solar cells [318, 319], and liquid crystals [320]. They are also interesting candidates for single-molecule device applications, such as sensors [321], molecular wires [322], or transistors [141].

Liquid Crystalline Semiconducting Polymers for Organic Field-Effect Transistor Materials... 

In this chapter, we mainly focus our discussion on conjugated polymers with liquid crystalline property as organic field-effect transistor materials. We will firstly give a briefly description of the transistor device and related physics. In the next session, the design strategy, property and performance of the LC polymers will be discussed to illustrate how hquid crystalline property of the polymer influences the overall performance of the device. Last but not least, we will end up our discussimi by providing a perspective on future research activities in this research area.

Liquid Crystals for Organic Field-Effect Transistors... 

Thermally and mechanically stable thin film formation is indispensable for fabrication of practical electronic devices such as organic light-emitting diodes, field-effect transistors, and particularly for flexible electronic papers. There are two approaches for formation of thermally and mechanically stable thin films. One is formation of glassy semiconductors retaining ordered structures by cooling from liquid-crystalline states [94]. The other approach is polymerization of liquid-crystalline semiconductors with a reactive moiety.
