We report an enzymatic sensor based on an organic electrochemical transistor that uses a room temperature ionic liquid as an integral part of its structure and as an immobilization medium for the enzyme and the mediator.

In the last four decades, substantial advances have been done in the understanding of the electrical behavior of excitable cells. From the introduction in the early 70's of the Ion Sensitive Field Effect Transistor (ISFET), a lot of effort has been put in the development of more and more performing transistor-based devices to reliably interface electrogenic cells such as, for example, cardiac m...

Three new linear benzene-fused bis(tetrathiafulvalene) compounds (1-3) were easily synthesized by one-step phosphite-induced cross-coupling reactions; a solution processed organic field-effect transistor based on 2 shows high mobility of 0.02 cm2/Vs.

Bigger and better: The new thin-film organic material octabenzcircumbiphenyl (OBCB; see scheme) forms an active layer in a field effect transistor, which can be switched simultaneously with two different inputs, that is, electrical bias and protonation.

1547 COVER Sunset for silicon? The push toward electronics that are smaller, faster, and more flexible requires either new inorganic and organic materials or new functionality for silicon and new transistor designs. See the special section beginning on page 1595.

The study of organic field effect transistors has expanded from its original objectives in developing organic semiconductors in which charge carriers have high mobility to focusing increasingly on opportunities arising from the design of electronic interfaces. Interfaces can have an important functional role in devices, for example a reconfigurable interface which responds reversibly to externa...

The advantages of organic field-effect transistors (OFETs), such as low cost, flexibility and large-area fabrication, have recently attracted much attention due to their electronic applications. Practical transistors require high mobility, large on/off ratio, low threshold voltage and high stability. Development of new organic semiconductors is key to achieving these parameters. Recently, organ...
