- Abstract
- Poly(9,9-dioctylfluorene) nanowire arrays with pronounced beta-phase were prepared by a one-step fabrication method, liquid-bridge-mediated nanotransfer molding. Liquid-bridge-mediated nanotransfer molding is a new direct nano-patterning method based on the direct transfer of various materials from a mold to a substrate via liquid layer. We fabricated poly(9,9-dioctylfluorene) nanowire arrays (80 nm parallel lines and 120 nm spaces) by Liquid-bridge-mediated nanotransfer molding using the poly(9,9-dioctylfluorene) ink solution. The formation of the beta-phase poly(9,9-dioctylfluorene) was proved by the present of an absorption peak at 435 nm. The most intense photoluminescence emission was obtained with the collection polarizer oriented parallel to the nanowire long axis, and an emission dichroic ratio of 3.7 was determined.
