Over the past several decades, organic conjugated materials as semiconductors in organic field effect transistors (OFETs) have attracted more and more attention from the scientific community due to their intriguing properties of mechanical flexibility and solution processability. However, the device fabrication technique, design, and synthesis of novel organic semiconductor materials with high charge carrier mobility is crucial for the development of high-performance OFETs. In the past few years, more and more novel materials were designed and tested in the OFETs. Among which, diketopyrrolopyrrole (DPP) and its derivatives, as the electron acceptors to build donor-acceptor (D-A) typed materials, are the perspective. In this article, recently reported molecules regarding the DPP and its derivatives for OFETs application are reviewed. In addition, the relationship between the chemical structures and the performance of the device are discussed. Furthermore, an outlook of DPP-based materials in OFETs with a future design concept and the development trend are provided.

Organic semiconductors (OSCs) are promising transducer materials when applied in organic field-effect transistors (OFETs) taking advantage of their electrical properties which highly depend on the morphology of the semiconducting film. In this work, the effects of OSC thickness (ranging from 5 to 15 nm) on the piezoresistive sensitivity of a high-performance p-type organic semiconductor, namely dinaphtho [2,3-b:2,3-f] thieno [3,2–b] thiophene (DNTT), were investigated. Critical thickness of 6 nm thin film DNTT, thickness corresponding to the appearance of charge carrier percolation paths in the material, was demonstrated to be highly sensitive to mechanical strain. Gauge factors (GFs) of 42 ± 5 and −31 ± 6 were measured from the variation of output currents of 6 nm thick DNTT-based OFETs engineered on top of polymer cantilevers in response to compressive and tensile strain, respectively. The relationship between the morphologies of the different thin films and their corresponding piezoresistive sensitivities was discussed.

The extraordinary physiochemical properties of carbon nanotubes (CNTs) stimulated their wide application in biosensing research. Nanotube characteristics of fast electron transport, large surface area, high strength, excellent catalytic activity and good chemical stability contribute to ultrasensitive, highly selective and stable CNT biosensors. Among the various CNT biosensors, the field-effect transistor (FET) architecture has received tremendous attention due to the advantages of high performance, miniaturization, and capability for mass production. In this paper, we address recent advances in the development of CNT biosensors based on FETs. The synthesis and properties of CNTs are discussed, along with their integration into biosensors. Recent progress in device fabrication, including CNT functionalization, attachment, and bioreceptor immobilization in CNT-based FET biosensors are highlighted. Examples in medical, food and environmental fields are illustrated.
