TECHNICAL SUMMARY:The fundamental objective of this research is to gain a detailed understanding of patterned conjugated materials in terms of their synthesis and characterization and application to advanced organic electronic devices. There can be no question that organic electronic materials themselves are of great interest with whole industries being created around such materials: technical applications in mind include, but are not limited to, OLED/PLED displays, organic transistors, low-cost devices, and organic materials for energy conversion. The studies outlined in this proposal will answer questions about new patterned conjugated semiconductor polymer layers. This project entails the detailed study of the chemical attachment of semiconducting layers to various substrates and their use to make operating devices. The long-term impact of the proposed research should be new insight into a new class of materials and the potential of easily fabricated devices with resolution unmatched by any currently known methods. The project research goals and outcomes: are; (1) the synthesis and characterization of patterned grafted brush layers of semiconducting polymers.; (2) an understanding of the morphology of grafted semiconducting brush layers as a function of molecular structure and molecular weight; (3) the development of a toolbox for the fabrication of active device structures on a variety of substrates; and (4) development of new device test structures that will allow the probing of electrical and optical properties of patterned semiconducting polymer layers. Our goals will be accomplished by the execution of three coupled subprojects: (1) we will exploit our skills in monomer and polymer synthesis to create and study new semiconducting polymers and generate surfaces modified by grafted semiconducting polymer layers or brushes.; (2) advanced patterning techniques will be developed allowing the unprecedented precise placement of these semiconducting layers for optimization of performance; and (3) we will combine our expertise in synthesis and processing to fabricate and test organic electronic devices. NON-TECHNICAL SUMMARY:Organic electronic materials themselves are of great interest with whole industries being created around such materials: technical applications in mind include, but are not limited to, advanced display devices, lost cost/ low power computing, and new materials for solar energy generation. The fundamental objective of this research is to gain a detailed understanding of a new class of polymeric organic electronic materials ? specifically how they are made and how can they be used to make better and less expensive devices potentially impacting industry, the economy, and our energy infrastructure. If successful, a new generation of materials and devices will be enabled and new opportunities for US companies and scientist to exploit these new technologies will be created. Our materials design and synthesis will add to the portfolio of exciting polymer research at the University of Massachusetts, and help facilitate research interactions between the University of Massachusetts and the microelectronics industry (equipment suppliers, materials suppliers, and end-users of nanolithography). Education of students and training them to help maintain US competitiveness in new areas of nanotechnology is another major impact of the study. These students will be trained in new techniques and learn not only traditional chemical synthesis and advanced characterization techniques, but also how these materials are integrated into actual industrial process development. The PI will generate new curricula and modify existing courses with information generated by this project. Funding will allow the PI to explore educational opportunities for local underrepresented minority children (Springfield, MA area) and part of the research developed in this proposal will be used to engage the minds and imaginations of young (8-14) children through weekend workshops. Finally, a network of New England Underrepresented Polymer/Material Scientists and Engineers will be formed. It is the intention that the network will be used by the PI and others to bring together students and professionals to find common goals in education and development.

技术摘要：本研究的基本目标是详细了解图案化共轭材料的合成、表征以及在先进有机电子器件中的应用。 毫无疑问，有机电子材料本身引起了人们的极大兴趣，围绕此类材料创建了整个行业：所考虑的技术应用包括但不限于 OLED/PLED 显示器、有机晶体管、低成本器件和有机电子材料。用于能量转换的材料。该提案中概述的研究将回答有关新型图案化共轭半导体聚合物层的问题。 该项目需要详细研究半导体层与各种基材的化学附着及其用于制造操作设备的用途。拟议研究的长期影响应该是对新型材料的新见解以及易于制造的设备的潜力，其分辨率是任何当前已知方法所无法比拟的。该项目的研究目标和成果：是； (1)半导体聚合物图案化接枝刷层的合成和表征； (2) 了解接枝半导体刷层的形态作为分子结构和分子量的函数； (3) 开发用于在各种基板上制造有源器件结构的工具箱； (4) 开发新的器件测试结构，以探测图案化半导体聚合物层的电学和光学特性。我们的目标将通过执行三个耦合子项目来实现：（1）我们将利用我们在单体和聚合物合成方面的技能来创建和研究新的半导体聚合物，并生成通过接枝半导体聚合物层或刷子改性的表面。 (2) 将开发先进的图案化技术，允许对这些半导体层进行前所未有的精确放置，以优化性能； (3)我们将结合我们在合成和加工方面的专业知识来制造和测试有机电子器件。 非技术摘要：有机电子材料本身引起了人们的极大兴趣，围绕此类材料创建了整个行业：所考虑的技术应用包括但不限于先进显示设备、成本损失/低功耗计算以及太阳能新材料能源产生。 这项研究的基本目标是详细了解一类新型聚合有机电子材料？具体来说，它们是如何制造的，以及如何使用它们来制造更好、更便宜的设备，从而可能影响工业、经济和我们的能源基础设施。 如果成功，新一代材料和设备将被启用，并为美国公司和科学家利用这些新技术创造新的机会。 我们的材料设计和合成将增加马萨诸塞大学令人兴奋的聚合物研究组合，并有助于促进马萨诸塞大学和微电子行业（设备供应商、材料供应商和纳米光刻最终用户）之间的研究互动。 对学生的教育和培训有助于保持美国在纳米技术新领域的竞争力是该研究的另一个主要影响。 这些学生将接受新技术培训，不仅学习传统的化学合成和先进的表征技术，还学习如何将这些材料集成到实际的工业过程开发中。 PI 将生成新课程并利用该项目生成的信息修改现有课程。 资金将使 PI 能够为当地代表性不足的少数族裔儿童（马萨诸塞州斯普林菲尔德地区）探索教育机会，并且该提案中开发的部分研究将用于通过周末研讨会吸引年幼（8-14 岁）儿童的思想和想象力。最后，将形成新英格兰代表性不足的聚合物/材料科学家和工程师网络。 PI 和其他人希望利用该网络将学生和专业人士聚集在一起，以找到教育和发展的共同目标。
