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.

这项研究努力巩固和扩大纳米结构聚合物材料的系统处理。 最具体地说，对于电形材料，将注意提高热/光化学稳定性和材料光学损失，同时继续改善电用量活性和材料加工性。 这将通过合并自由基清除部分并实现更系统的交联，利用树突超分子构建块的结构特征。 从先前的研究中汲取的经验教训将继续改善发色团。 此外，还将进行改善的八度极性以及偶极，发色团的发展。 发色体配体将用于开发新的两光子聚合物材料，这些材料具有创纪录的光学非线性水平，可用于传感器保护，光学回路制造，医学成像和超快全光开关。 树突状配体还将继续开发，以进一步完善与光学扩增和太阳能电池应用相关的光收集。 %% %%这项研究以一个共同的理论基础和模块化方法捆绑在一起，该方法允许将材料组件应用于多种应用。 多种使用材料和纳米结构构建概念的开发使我的一项相对较小但专注的材料研究工作能够对许多不同的技术产生高影响。
