Abstract
Organic crystal microwires (OCMs) have attracted much attention in the last decade due to their great potential for fabricating high-performance organic field-effect transistors (OFETs) and related applications including circuits, displays, sensors, as well as flexible and wearable devices. OCMs offer a number of advantages, such as long-range ordering, the absence of grain boundaries, low defect density, and flexibility. However, the preparation of tiny-sized, highly crystalline and homogeneous ribbons faces considerable challenges. Therefore, efforts have been made to develop new processing methods to produce high-quality OCMs. This perspective describes recent simple and widely used techniques for the preparation of OCMs, including both dry and wet processes. The advantages and limitations of these different techniques are discussed. In addition, we summarize recent advances in the performance of OCMs-based OFETs, comparing the charge-transporting properties of different preparation methods, including OCMs and thin films. Finally, the potential and future prospects of utilizing crystal microwires in perovskite FETs are also discussed.
