Organic thin films with high performance require three-dimensional (3D) regulation of the position and the orientation of molecules in organic thin films. The 3D regulation appears to be feasible by combination of one-dimensional out-of-plane regulation and two-dimensional in-plane alignment. The out-of-plane regulation involves the molecular layer epitaxy method firstly demonstrated by the author, and the out-of-plane alignment can be controlled by the interfacial anisotropy induced by the external electric field, the substrate crystal structure and the rubbing of the substrate surface. The electric and optical properties of these films are investigated. The mechanism of the specific structure formation is discussed from the quartz crystal microbalance study on the basis of a novel theoretical model.

高性能有机薄膜需要对有机薄膜中分子的位置和方向进行三维（3D）调控。通过一维面外调节和二维面内对准的组合，3D 调节似乎是可行的。面外调控涉及作者首次论证的分子层外延方法，面外取向可以通过外部电场、衬底晶体结构和摩擦力引起的界面各向异性来控制。基材表面。研究了这些薄膜的电学和光学性质。基于新颖的理论模型，从石英晶体微天平研究中讨论了特定结构形成的机制。
