"Crosslinking agents are electrically non-conductive, and therefore the addition of a large amount of a crosslinking agent leads to a morphological change in the film and deterioration in the electrical and optoelectronic properties of the material," says Professor Kim. "However, the new crosslinker can be applied to the patterning process of various solution-processable materials with use of a very low amount is thus highly desirable. Using a very small amount of 4Bx, the research team has succeeded in fabricating highly integrated arrays of polymer thin-film transistors (PTFTs) and logic circuits via all-solution processing. The results show that the PTFTs based on photocrosslinked polymer films show equivalent performance and better stability compared with those prepared using polymer films without the crosslinker. "Overall, this work demonstrates an effective route to all-solution-processed organic electronic devices based on a single fabrication protocol," says Professor Kim. The findings of this research have been published in the online version of Nature Communications.
