Abstract:

We present an all-additive manufg. method that is performed at mild conditions, for the formation of org. single crystals at specific locations, without any photolithog. prefabrication process. The method is composed of two steps; inkjet printing of a confinement frame, composed of a water sol. electrolyte. Then, an org. semiconductor soln. is printed within the confinement to form a nucleus at a specific location, followed by addnl. printing, which led to the growth of a single crystal. The specific geometry of the confinement enables control of the specific locations of the single crystals, while sepg. the nucleation and crystal growth processes. By this method, we printed single crystals of perylene, which are suitable for the formation of OFETs. Moreover, since this method is based on a simple and controllable wet deposition process, it enables formation of arrays of single crystals at specific locations, which is a prerequisite for mass prodn. of active org. elements on flexible substrates.
