Solution processed organic field-effect transistors and their application in printed logic circuits

Manufacturing organic circuits from solution provides an opportunity to realize low-cost fabrication of large-area flexible electronics, such as radio frequency identity tags, sensor arrays and flexible displays. Inspired by the potential applications, significant efforts have been devoted to develop organic field-effect transistors with solution processed components in the past decade. Herein, we summarize recent progresses in solution processable functional materials including organic semiconductors, electrode materials, and dielectric materials. Various solution manufacturing techniques, patterning techniques and related device engineering methods are also reviewed. Finally, all-solution processed logic circuits are discussed from the point of view of practical application. All these achievements represent a big step forward and promise the solution processed OFETs a bright future.
