This research endeavors to consolidate and extend gains in the systematic processing of nanostructured polymeric materials. Most specifically, for electro-optic materials, attention will be paid to improving thermal/photochemical stability and material optical loss, while continuing to improve electro-optic activity and material processability. This will be accomplished by incorporating free radical scavenging moieties and effecting more systematic crosslinking exploiting the structural features of dendritic supramolecular building blocks. Chromophores will continue to be improved exploiting lessons learned from previous research. Moreover, the development of improved octupolar, as well as dipolar, chromophores will be undertaken. Chromophore ligands will be used to develop new two-photon polymeric materials exhibiting record levels of optical nonlinearity, which can be exploited for sensor protection, optical circuit fabrication, medical imaging, and ultrafast all-optical switching. Dendritic ligands will also continue to be developed to further refine light harvesting relevant to optical amplification and solar cell applications. %%%This research is tied together by a common theoretical basis and by a modular approach that permits material components to be applied to several applications. The development of multiple use materials and nanostructural construction concepts my enable a relatively small, but focused, materials research effort to have high impact on a number of diverse technologies.

这项研究致力于巩固和扩展纳米结构聚合物材料系统加工方面的成果。 最具体地，对于电光材料，将关注提高热/光化学稳定性和材料光学损耗，同时继续提高电光活性和材料可加工性。 这将通过结合自由基清除部分并利用树枝状超分子构件的结构特征进行更系统的交联来实现。 发色团将利用先前研究的经验教训继续改进。 此外，还将开发改进的八极和偶极发色团。 发色团配体将用于开发新型双光子聚合物材料，该材料表现出创纪录的光学非线性水平，可用于传感器保护、光电路制造、医学成像和超快全光开关。 树突配体还将继续开发，以进一步完善与光学放大和太阳能电池应用相关的光捕获。 %%%这项研究通过共同的理论基础和允许材料组件应用于多种应用的模块化方法联系在一起。 多种用途材料和纳米结构构造概念的发展可以使相对较小但集中的材料研究工作对许多不同的技术产生重大影响。
