Abstract
The present invention provides ink-jet printing ink for organic semiconductors, and, more particularly, provides ink-jet printing ink for organic semiconductors, which can be used to form a uniform crystalline thin film. The ink-jet printing ink of the present invention includes a mixed solvent composed of a first solvent and a second solvent having a higher boiling point and lower surface tension than the first solvent, thus forming a uniform crystalline thin film in a volatilization process. Further, the present invention provides a circular organic thin film transistor having a high field-effect mobility of about 0.12 cmVS.
