Development of Universal Three-Dimensional Crosslinker for All-Photopatterned Electronics |
| 초록 |
Fabrication of electronic components at high resolution remains a challenging task for organic electronic devices fabricated entirely through a series of solution processes. We report the all-solution processing of highly integrated arrays of polymer thin-film transistors (PTFTs) and logic gates. This processing is performed using a newly developed 4Bx crosslinker containing four-branched photocrosslinkable units. Under UV, 4Bx molecules mixed within solution-processable electronic materials generate a three-dimensional (3D) network of the given material. We note that this 4Bx crosslinker can produce the 3D network state efficiently even at an unprecedentedly small loading, which, in turn, enables preservation of the intrinsic electrical properties of the photocrosslinked material. Moreover, the crosslinked electronic component layers allows not only micropatterning of the layers at high resolution but also stacking of a given electronic component layer on top of the other layers. |
