Technical abstractThis project is to develop a unique system for microlithography of organic materials from solution using a direct-write process. The instrument will be capable of depositing a variety of materials, including organic semiconductors, functionalized proteins, and polymeric materials. The work will build on a recent discovery that by directing the crystallization of thin film materials laterally across the surface of a substrate, crystalline domain sizes larger than one millimeter can be obtained for a variety of organic semiconductor materials. The large grain sizes represent a several order-of-magnitude improvement over commonly used techniques. Single crystal films have much lower defect densities than polycrystalline films, and exhibit improved electronic and mechanical properties. Thus, the goal of several research projects that will use this new instrument will be to correlate structural ordering of new materials with electrical, optical, and mechanical properties. The materials to be studied initially have applications in the areas of organic electronics, organic photovoltaics, synthetic collagen, and biocompatible materials that could be used for stents. The capability to easily fabricate highly ordered thin films of new materials will enable rapid progress in both fundamental studies of materials and the development of new materials for applications in the areas mentioned above.Non-technical abstractThis project is to develop a system that implements a new inexpensive method for writing patterns of carbon-based soft materials with a high degree of alignment of the molecules making up the material. The ordering arrangement of molecules has a large influence on the properties of the materials and hence the suitability for practical applications. The new instrument will allow research on how certain types of molecular ordering influence properties of materials that might make them suitable for forming electronic switches, or to generate electricity from light. The instrument will produce a much higher degree of ordering than conventional methods, and will therefore assist in the development of materials for bright inexpensive displays, as well as for highly efficient carbon-based solar cells as a source of electricity. Other materials that will be investigated have applications as synthetic strands of the material that give skin its elastic properties, and as bio-compatible materials that can be used for hold blocked arteries open to allow blood to flow freely. The crucial capability to easily fabricate highly ordered thin films of a broad range of materials will enable rapid progress in both fundamental studies and advanced applications in the areas mentioned above.

技术摘要该项目是使用直接写入过程从溶液中开发出有机材料微观造影的独特系统。 该仪器将能够沉积多种材料，包括有机半导体，功能化蛋白质和聚合物材料。这项工作将基于最近的发现，即通过将薄膜材料的结晶在底物的表面上，可以在各种有机半导体材料中获得大于1毫米的结晶域大小。与常用技术相比，大谷物尺寸代表了几种刻度级的改进。单晶膜的缺陷密度比多晶膜低得多，并且具有改善的电子和机械性能。 因此，将使用该新工具的几个研究项目的目标是将新材料的结构排序与电气，光学和机械性能相关联。 最初需要研究的材料在有机电子，有机光伏，合成胶原蛋白和生物相容性材料的区域中有应用，可用于支架。 在材料的基本研究和开发新材料的新材料中，在上述领域的应用开发新材料的新材料的薄膜易于制造的能力将能够快速进步。Non-technical Abstrackthis Project是开发一种实现一种新的廉价方法，用于编写基于碳的软材料的碳基材料模式，并具有高度的材料构成材料的材料。分子的订购布置对材料的性质有很大影响，因此适合实际应用。新仪器将允许研究某些类型的分子排序如何影响材料的特性，从而使其适合形成电子开关或从光发电。 该仪器将产生比常规方法更高的订购程度，因此将有助于开发明亮的廉价显示器以及高效的碳基太阳能电池作为电力来源。其他将要研究的材料将应用作为材料的合成链，这些材料具有赋予皮肤弹性特性的材料，以及可用于固定动脉的生物兼容材料，以允许血液自由流动。易于制造高度有序材料的高度有序薄膜的关键能力将在基本研究和上述领域的高级应用中快速进步。
