본 논문에서는 유기전자소자의 반도체 물질로 많이 사용되는 poly(9,9-dioctylflurorene) (PFO), poly(9,9-dioctylfluorene-co-benthiadiazole) (F8BT), (regioregular poly(3-hexylthiophene) (P3HT)를 기반으로 하는 균일한 크기와 특성을 가지는 고분자 나노와이어를 AAO 템플레이트를 이용하여 대량으로 제작하였다. 제작된 나노와이어는 결점이 없이 깨끗한 표면을 보였으며, 약 250~300 nm의 지름과 ${\sim}30{\mu}m$의 일정한 길이를 가지고 있었다. 나노와이어들은 스프레이 분사 방법을 통하여 유리 기판 위에 균일하게 분사할 수 있었으며, PFO와 F8BT 나노와이어의 경우 UV 빛의 조사하에 각각 나노와이어의 전체에 걸쳐서 왜곡없이 밝은 yellow와 blue luminescence를 보였다.

Recent work in our laboratory has focused on the molecular and supramolecular engineering of conjugated polymers and oligomers for device applications, including light emitting diodes for displays and lighting, photovoltaic cells, and thin film transistors. A central finding is that the supramolecular structure of conjugated polymers can have a dominant influence on their properties and the performance of devices. Some major results include: highly efficient RGB light-emitting diodes from polymers and oligomers; high mobility n-channel polymer field effect transistors; ambipolar thin film transistors from copolymer semiconductors; and self-assembly and ambipolar charge transport in polymer nanowires.

We fabricate poly(3,4-ethylenedioxythiopene patterns using liquid-bridge-mediated nanotransfer (LB-nTM) printing via vapor phase polymerization (VPP). LB-nTM printing method can simultaneously enable the synthesis, alignment and patterning of the nanowires from molecular ink solutions. Two- or three-dimensional complex structures of VPP-PEDOT were directly fabricated over a large area using many types of molecular inks. VPP method is a versatile technique that can be used to obtain highly conducting coatings of conjugated polymer on both conducting and non-conducting substrates. The PEDOT patterns has analyzed crystallinity from X-ray diffraction pattern and select-area diffraction patterns. In addition, the PEDOT pattern has high conductivity compared other conducting polymers.
