Themed collection Organic Field Effect Transistors

This themed issue presents a collection of articles on organic field-effect transistors: interfacial phenomena and electronic properties.

The use of charge transfer salts in OFETs offers unique possibilities for enhancing the device performance.

In this perspective article, we provide a recent overview of the route to realize high-performance printed organic transistors and integrated circuits.

CuTCNQ microribbons prepared by a controllable and solution-processed method give rise to interfacial energetic match with organic semiconductor.

A novel asymmetric naphthalimide derivative (IZ0) is synthesized and high electron mobility of 0.072 cm² V⁻¹ s⁻¹ and 0.22 cm² V⁻¹ s⁻¹ are achieved for IZ0 film and single crystal-based transistors, respectively.

Hole mobilities greater than 0.1 cm² V⁻¹ s⁻¹ are attained in films that contain over 80% oligomer.

Surfactant treatment of the poly(vinyl alcohol) gate insulator enhances the field-effect mobility of poly(3-hexylthiophene-2,5-diyl) transistors.

Not only do we report two new polymers (PIIG-DTBT and PIIG-DSeBT) involving isoindigo and benzothiadiazole blocks constructed with thiophene and selenophene spacers, but also explore the optical, electrochemical, and charge-transport properties.

Effects of contact-area-limited doping for pentacene thin-film transistors with a bottom-gate, top-contact configuration were investigated.

Easily reducible tetracyano-substituted (thieno)isoindigo small molecules were synthesized. A tetracyanothienoisoindigo exhibits electron mobility value up to 0.09 cm² V⁻¹ s⁻¹ in inkjet-printed OFETs and its spin-coated devices have been shown to operate in air.
