New quantum and statistical mechanical methods will be applied to the rational design of electro-optic materials with the target of achieving electro-optic activity of 1000 pm/V at telecommunication wavelengths together with optical loss of less than 2 dB/cm and material glass transition temperatures of greater than 180 degees C. Material performance targets are critical for implementation of next generation defense, homeland security, and information technologies. Theoretically-inspired chromophores will be synthesized, including by microwave-assisted protocols, and incorporated into dendritic and dendronized polymer supermolecular lattices that are, in turn, designed to promote noncentrosymmetric organization of the chromophores. Material lattices will be hardened through Retro-Diels-Alder and fluorovinyl ether crosslinking chemistries. Appropriate proof-of-concept calculations and synthetic methods have been demonstrated. Materials will be transitioned to government, industry, and other academic laboratories for incorporation into a variety of devices including devices utilizing nanoscopic silicon photonic circuitry. In addition to contributing the training of undergraduate and graduate students at the University of Washington, the principal investigator is actively involved in mentoring a number of high schools students and in working with minority serving institutions (Norfolk State University, Alabama A&M University, and Heritage College) in developing their research and education programs including new graduate degree programs.%%%Modern defense platforms, imbedded network sensing, and information technology (computer chips; data management and communication networks) increasingly involve simultaneous utilization of electronics and photonics. High bandwidth, low power electro-optic conversion is critical to this process. New theoretical methods will be used to achieve a factor of 30 improvement of electro-optic efficiency of polymeric materials in the proposed three year program of coordinated material design, synthesis, and characterization. The practical objective is to dramatically advance the fundamental understanding of electrostatic forces that define material (super/supramolecular) nanostructure (and resultant photonic and electronic properties) and to exploit that understanding to achieve new materials enabling record data handling rates of greater than 100 Gb/s with control voltages of less than 1 volt and optical powers of a few milliwatts. These requirements are critical for phased array radar and for sensing and information management systems (Defense, Homeland Security, and Information Technologies). The research conducted in this project is relevant to future commercial products of Boeing, Lockheed Martin, Intel, and other companies both large and small. The project will advance the training and ultimate job placement of high school, undergraduate, and graduate students. Moreover, the principal investigator is actively involved in working with minority serving institutions (Norfolk State University, Alabama A&M University, and Heritage College) to enhance their education and research activities, including development of new degree programs, critical for training of the Nation's technology workforce and enhancing the diversity of that workforce.

新的量子和统计力学方法将应用于电光材料的合理设计，目标是在电信波长下实现 1000 pm/V 的电光活性，同时光学损耗小于 2 dB/cm，材料玻璃化转变温度大于 180 摄氏度。材料性能目标对于实现下一代国防、国土安全和信息技术至关重要。 受理论启发的发色团将被合成，包括通过微波辅助方案，并将其纳入树枝状和树枝状聚合物超分子晶格中，而这些晶格反过来又被设计为促进发色团的非中心对称组织。 材料晶格将通过 Retro-Diels-Alder 和氟乙烯基醚交联化学物质硬化。 适当的概念验证计算和合成方法已经得到证实。 材料将被转移到政府、工业界和其他学术实验室，用于整合到各种设备中，包括利用纳米硅光子电路的设备。 除了为华盛顿大学本科生和研究生的培训做出贡献外，首席研究员还积极参与指导一些高中生，并与少数族裔服务机构（诺福克州立大学、阿拉巴马农工大学和遗产学院）合作开发他们的研究和教育项目，包括新的研究生学位项目。%%%现代防御平台、嵌入式网络传感和信息技术（计算机芯片；数据管理和通信） 网络）越来越多地涉及电子学和光子学的同时利用。 高带宽、低功耗电光转换对此过程至关重要。 在拟议的协调材料设计、合成和表征的三年计划中，将使用新的理论方法将聚合物材料的电光效率提高 30 倍。 实际目标是极大地推进对静电力的基本理解，静电力定义了材料（超/超分子）纳米结构（以及由此产生的光子和电子特性），并利用这种理解来实现新材料，能够在小于 1 伏的控制电压和几毫瓦的光功率下实现大于 100 Gb/s 的记录数据处理速率。 这些要求对于相控阵雷达以及传感和信息管理系统（国防、国土安全和信息技术）至关重要。 该项目中进行的研究与波音、洛克希德·马丁、英特尔和其他大大小小的公司的未来商业产品相关。 该项目将促进高中生、本科生和研究生的培训和最终就业安置。 此外，首席研究员还积极参与与少数族裔服务机构（诺福克州立大学、阿拉巴马农工大学和传统学院）合作，以加强他们的教育和研究活动，包括开发新的学位课程，这对于培训国家技术劳动力和增强劳动力的多样性至关重要。
