“…6(a). Compared to all the other scalable solution‐processable methods, spray‐coating is eligible for ultrathin film formation at very large scale 96,114 . Although cost‐effective and fast, spray‐coating inherently suffers from a microscale stochastic process such as a complex droplet inflight and impact dynamic process 60 .…”

In the past decades, a variety of organic field‐effect transistor (OFET) based sensors have been reported, holding great promise in physical sensing, chemical sensing, biosensing, medical sensing and functionalized integrated sensor arrays, thanks to the superiorities of OFETs, including fabrication versatility and high sensitivity to external stimulus. However, the sensing performance still needs to be enhanced to meet practical application requirements, especially high sensitivity and short response time. Among all the effective strategies, ultrathin organic semiconductor (OSC) film devices show significantly promoted sensing performance, and the fabrication methods to obtain these ultrathin OSC films are of importance and diversity. Here, a brief review focused on ultrathin (including molecular monolayer) OSC film fabrication methods is presented, including high‐vacuum thermal evaporation, solution‐processable methods, and the approach of combining ultrathin films with heterojunctions. Additionally, applications of ultrathin OFET‐based chemical and biological sensors are summarized. Finally, the outlook and challenges ahead are discussed. We hope this review can offer guidance for the fabrication methods and potential applications of ultrathin OFET‐based chemical and biological sensors in the future. © 2020 Society of Industrial Chemistry

“…[81][82][83][84] Compared with linear polymer dielectrics, cross-linked high-k polymers are more suitable for the preparation of an integrated circuit by a solution process due to their excellent organic solvent resistance. 85,86 To achieve the cross-linking of a polymer, various methods have been developed, including the esterification reaction, the ring-opening reaction of epoxy resin and the click chemical reaction of thiolene. [87][88][89][90][91] Next, common methods used to fabricate cross-linked polymer dielectrics at low temperature and the effects of crosslinking a polymer on its dielectric properties are discussed.…”

“…One approach to circumvent this is to apply direct heating control to the printing equipment, such as metal drums and rollers. Heating the backing roller onto which OE inks are deposited in a controlled fashion has been shown to substantially improve both photovoltaic [144] and transistor device per-formance [145]. This improvement is achieved by fine-tuning the rate at which inks dry and controlling the kinetics of the glass transition in the molecules to induce nanoscale control of the semiconducting material crystallinity and domain size.…”

Printed electronics is simultaneously one of the most intensely studied emerging research areas in science and technology and one of the fastest growing commercial markets in the world today. For the past decade the potential for organic electronic (OE) materials to revolutionize this printed electronics space has been widely promoted. Such conviction in the potential of these carbonbased semiconducting materials arises from their ability to be dissolved in solution, and thus the exciting possibility of simply printing a range of multifunctional devices onto flexible substrates at high speeds for very low cost using standard roll-to-roll printing techniques. However, the transition from promising laboratory innovations to large scale prototypes requires precise control of nanoscale material and device structure across large areas during printing fabrication. Maintaining this nanoscale material control during printing presents a significant new challenge that demands the coupling of OE materials and devices with clever nanoscience fabrication approaches that are adapted to the limited thermodynamic levers available. In this review we present an update on the strategies and capabilities that are required in order to manipulate the nanoscale structure of large area printed organic photovoltaic (OPV), transistor and bioelectronics devices in order to control their device functionality. This discussion covers a range of efforts to manipulate the electroactive ink materials and their nanostructured assembly into devices, and also device processing strategies to tune the nanoscale material properties and assembly routes through printing fabrication. The review finishes by highlighting progress in printed OE devices that provide a feedback loop between laboratory nanoscience innovations and their feasibility in adapting to large scale printing fabrication. The ability to control material properties on the nanoscale whilst simultaneously printing functional devices on the square metre scale is prompting innovative developments in the targeted nanoscience required for OPV, transistor and biofunctional devices.
