Replacing or minimizing the use of halogenated organic solvents in the processing and manufacturing of conjugated polymer based organic electronics has emerged as an important issue. To date, however, the processing of well-ordered conjugated polymer nanostructures has been difficult to achieve using environmentally benign solvents. In this work, we report the development of water and alcohol processable nanowires (NWs) with well-defined crystalline nanostructure based on the solution assembly of azide functionalized poly(3-hexylthiophene) (P3HT-azide), and subsequent photo-crosslinking and functionalization of these NWs with alkyne terminated polyethylene glycol (PEG-alkyne). PEG functionalization of the crosslinked P3HT-azide NWs allowed for stable dispersion in alcohols and water, while maintaining well-ordered NW structures with electronic properties suitable for the fabrication of organic field effect transistors (OFETs). |
