TECHNICAL SUMMARY: Multi-scale theoretical (time-dependent density functional theory and coarse-grained Monte Carlo-molecular dynamics) methods are being developed and will used to guide the development of new macromolecular (polymer and dendrimer) electroactive materials with particular focus on electro-optic materials critical for chipscale integration of electronics and photonics. Theory-guided design will permit control of both molecular architecture (molecular order and lattice dimensionality) and dynamics (viscoelasticity and phase transitions). New experimental methods are being developed to characterize order, lattice dimensionality, and viscoelasticity. Newly synthesized and characterized organic electro-optic materials will be integrated with silicon photonic, plasmonic, and metamaterial devices relevant to telecommunications, computing, and sensing technologies. Collaboration with the Air Force Research Laboratory, industry (Boeing, Intel, and other companies), and with international researchers (Germany, Switzerland, Belgium) will be pursued. Workforce development and promotion of workforce diversity will be pursued through continued interactions with minority serving institutions including HBCUs (e.g., Norfolk State University), Hispanic and Native American institutions. Undergraduate and high school student participation in research will also be facilitated. The potential broader economic impacts of science will be emphasized by working with the UW Center for Innovation and Technology Entrepreneurship.NON-TECHNICAL SUMMARY: Properties of electroactive (e.g., photovoltaic, electronic, electro-optic) materials depend on the organization of component atoms, ions, or molecules. The utilization of soft matter materials has been inhibited by lack of theory-guided design to achieve the desired order and performance properties. New theoretical methods will be developed that will permit such rational design leading to new electro-optic materials and permitting the fabrication of compact information technology devices exhibiting ultrahigh-speed and low power-consumption data processing. Such technology is important to chipscale integration of electronics and photonics, and in turn to next-generation computing, telecommunications, and sensing technologies. The anticipated outcome of this basic research program should be of potential interest to industry. Workforce development and enhancement of workforce diversity will be pursued through a variety of mechanisms including continued interaction with HBCUs (e.g., Norfolk State University), Hispanic, and Native American institutions, and through facilitation of the participation of undergraduate and high school students in research. Broader impact will also be achieved through the University of Washington Center for Innovation and Technology Entrepreneurship.

技术摘要：正在开发多尺度理论（时间依赖性密度功能理论和粗粒度的蒙特卡洛 - 分子动力学）方法，并将用于指导新的大分子分子（聚合物和树突生物元）的电动材料的开发，特别关注对奇普斯卡尔集成电子和光照相的电力材料。 理论指导的设计将允许控制分子结构（分子顺序和晶格维度）和动力学（粘弹性和相变）。 正在开发新的实验方法来表征顺序，晶格维度和粘弹性。 新合成和特征的有机电气材料将与硅光子，等离子和超材料设备集成与电信，计算和传感技术有关的。 与空军研究实验室（波音，英特尔和其他公司）以及国际研究人员（德国，瑞士，比利时）的合作。 通过与HBCUS（例如诺福克州立大学），西班牙裔和美国原住民机构在内的少数派服务机构的持续互动，将追求劳动力发展和促进劳动力多样性。本科生和高中生的研究也将得到促进。 通过与UW创新和技术创业中心合作，将强调科学的潜在更广泛的经济影响。非技术摘要：依赖于组件原子，离子，离子或分子的组织的电活性（例如光伏，电子，电子，电子电气）材料的特性。 由于缺乏理论指导的设计来实现所需的顺序和性能特性，软物质材料的利用受到了抑制。 将开发出新的理论方法，该方法将允许这种合理的设计导致新的电彩材材料，并允许制造具有超高速度和低功耗数据处理的紧凑型信息技术设备。 这种技术对于电子和光子学的芯片刻板集成很重要，进而对下一代计算，电信和传感技术很重要。 这项基础研究计划的预期结果应该引起行业的潜在兴趣。 劳动力发展和劳动力多样性的增强将通过各种机制来追求，包括与HBCUS（例如诺福克州立大学），西班牙裔和美国原住民机构的持续互动，以及通过促进大学生和高中生研究的参与。 华盛顿大学创新与技术企业家中心也将实现更大的影响。
