Solution-processed crystalline organic integrated circuits

The major advantages of organic electronics are their solution processability and unique optoelectronic performance. The long-range ordered single-crystal organic semiconductor provides the best device performance, as it guarantees efficient charge injection and transport and minimum defect states. Thus, a facial solution -printing-based method to fabricate single-crystal organic devices and circuits is of great importance to the development of organic electronics, but its development is still challenging. Herein, we propose a general strategy to construct an organic single-crystal device array entirely by solution-based methods. Taking organic field-effect transistors (OFETs) as an example, the recent progress of organic crystal fabrication, patterning, and high-resolution printed contacts is summarized. Finally, future research directions for this field are suggested.
