Outline of Final Research Achievements

The purpose of this project is to produce, deposit, and allocate independent single molecular bilayers, composed of amphiphilic asymmetric organic molecules, by printing technologies that attract considerable attentions as novel useful methods for thin-film formation and patterning of electronic functional materials. We first found that specific amphiphilic molecules, composed of relatively large pi-electron skeletons linked with alkyl chains, form a unique molecular-bilayer-type molecular packing, and is well fitted with uniform thin-film formation by the solution method. We also found that the intermolecular interactions between alkyl chains take crucial roles in the formation of the bilayer-type packing motif. Based on the findings, we successfully developed a unique solution-based technology to manufacture self-assembled ultrathin single molecular bilayers over an area as large as wafer scale, by using a mixed solution of molecules with different alkyl chain lengths.
