Porphyrin-Based Supramolecular Assemblies and Arrays - Model Systems for the Construction of Photosynthetic Mimics. Crown ether-based multichromophoric systems will be used to mimic the steps through which plants convert light into chemical energy. The crown bridging units allow a variety of metal and organic cations, which provide electronic and structural roles, to be non-covalently bound within their cavities. These systems are advantageous over other photosynthetic models in that a variety of electron transfer mediators can be examined in a readily controlled and systematic way simply through the choice of cation. In this way, the role played by molecular recognition in the modulation of long-range electron transfer can be evaluated. This work will lead to designing better artificial solar energy converters and molecular electronic devices.

基于卟啉的超分子组件和阵列-用于光合模拟构建的模型系统。基于冠醚的多色系统将用于模拟植物将光转化为化学能的步骤。冠桥单元允许各种提供电子和结构作用的金属和有机阳离子在其腔内非共价结合。这些系统比其他光合作用模型更有优势，因为各种电子传递介质可以通过简单地选择阳离子以一种容易控制和系统的方式进行检测。通过这种方式，可以评估分子识别在远程电子转移调制中所起的作用。这项工作将有助于设计更好的人工太阳能转换器和分子电子器件。
