Development of Synthesis, Processing, and Characterization Techniques for Next Generation Electroactive Materials

本研究旨在巩固和扩展纳米结构聚合物材料系统加工方面的成果。最具体地说，对于电光材料，将注意改善热/光化学稳定性和材料光学损耗，同时继续改善电光活性和材料可加工性。这将通过结合自由基清除部分和利用树突超分子构建块的结构特征进行更系统的交联来实现。利用以往研究的经验教训，发色团将继续得到改进。此外，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的双光子聚合物材料，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、光学电路制造、医学成像和超快全光开关。树突配体也将继续发展，以进一步完善与光学放大和太阳能电池应用相关的光收集。这项研究通过共同的理论基础和模块化的方法联系在一起，这种方法允许材料组件应用于多种应用。多用途材料和纳米结构结构概念的发展使相对较小但重点突出的材料研究工作对许多不同的技术产生了重大影响。

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.
