 Organic single crystal have been interested for various devices, such as photonic devices and electronic devices, due to their improvement of performance compared to amorphous or poly-crystal statement. In our previous study, we fabricated single crystal nanowire with liquid-bridge-mediated nanotransfer molding. Fabricated organic single crystal nanowire device shown very high performance and have high crystallinity.
 In this study, we analyzed that the crystallinity of 6,13-bis(triisopropylsilylethynyl) pentacene (TIPS-PEN) is depends on the pattern size of mold to make sure that the enhancement of crystallinity is from nanoconfinement effect. We fabricated various sized mold and synthesis TIPS-PEN wires with the molds. The synthesized wires have been investigated by scanning electron microscopy (SEM) and crystallinity of wires have been analyzed by selective-area electron diffraction (SAED).
 We fabricate field-effect transistors (FET) to compare the performance organic film devices with nanowire devices, and show the nanowire devices have very high-performance. Also, we fabricate high-performanced nanowire inverter with fullerene (C60).
