“…In addition, the growth of single crystals on interfaces has been controlled through manipulating the rate of evaporation and resulting local supersaturation [44]. Our approach with 1 bears similarities with the aforementioned, although the manipulation has been extended to three dimensions in common gelation conditions, and the degree of control is based on local thermal manipulation of the substrate for nucleation-growth and inherent properties of these systems.…”

Development of high‐performance organic electronic and optoelectronic devices relies on high‐quality semiconducting crystals that have outstanding charge transport properties and long exciton diffusion length and lifetime. To achieve integrated device applications, it is a prerequisite to precisely locate the organic semiconductor crystals (OSCCs) to form a specifically patterned structure. Well‐patterned OSCCs can not only reduce leakage current and cross‐talk between neighboring devices, but also facilely integrate with other device elements and their corresponding interconnects. In this Review, general strategies for the patterning of OSCCs are summarized, and the advantages and limitations of different patterning methods are discussed. Discussion is focused on an advanced strategy for the high‐resolution and wafer‐scale patterning of OSCC by a surface microstructure‐assisted patterning method. Furthermore, the recent progress on OSCC pattern‐based integrated circuities is highlighted. Finally, the research challenges and directions of this young field are also presented.

“…For instance, alignment using inkjet printing is restricted by the registration capability of the instrument, whereas the size of each OTFT is limited by the droplet size attainable (22,31). Another potential issue with these methods is the variance in electrical characteristics of TFTs due to the difficulty in obtaining uniform crystal growth on isolated TFTs over large areas (9,15,21,27,28,(31)(32)(33)(34)(35). Even single crystalline domains of patterned TFTs may have large variability in electrical characteristics as a result of random orientation and size variance.…”

The electronic properties of solution-processable small-molecule organic semiconductors (OSCs) have rapidly improved in recent years, rendering them highly promising for various low-cost largearea electronic applications. However, practical applications of organic electronics require patterned and precisely registered OSC films within the transistor channel region with uniform electrical properties over a large area, a task that remains a significant challenge. Here, we present a technique termed "controlled OSC nucleation and extension for circuits" (CONNECT), which uses differential surface energy and solution shearing to simultaneously generate patterned and precisely registered OSC thin films within the channel region and with aligned crystalline domains, resulting in low device-to-device variability. We have fabricated transistor density as high as 840 dpi, with a yield of 99%. We have successfully built various logic gates and a 2-bit halfadder circuit, demonstrating the practical applicability of our technique for large-scale circuit fabrication.organic semiconductors | patterning | small molecules | transistors | circuits
