Synthesis and Characterization of Dicyanoanthracene- Substituted-Beta-Cyclodextrins

9412515威廉和玛丽Abelt学院 将合成其中9，10-二氰基蒽被β-环糊精束缚、封端和夹在中间的超分子主体。主体和猝灭客体之间的相互作用将通过荧光光谱法进行研究。将开发几种分析方法来阐明静态和动态淬火组件。最终目标是确定导致强结合和大的静态/动态猝灭比的结构基序。这样的主体将是理想的光诱导电子转移催化剂。 来自有机动力学计划的这笔赠款支持威廉和玛丽学院的克里斯托弗·J·阿贝尔特教授的持续工作。在紫外光照射下可以接受电子的悬垂有机分子将与圆锥形碳水化合物分子键合。碳水化合物分子可以作为其他分子（客人）的宿主，这些分子可以适应这个圆锥形的宿主。客体分子将是电子供体，使得在照射时，电子将从客体转移到侧有机分子。由于主体的体积限制了客体分子的场，因此将发生选择性电子转移。

9412515 Abelt College of William and Mary Supramolecular hosts in which 9,10-dicyanoanthracene is tethered, capped, and sandwiched with beta-cyclodextrin will be synthesized. The interaction between the hosts and quenching guests will be studied by spectrofluorimetry. Several analytical methods will be developed to elucidate the static and dynamic quenching components. The ultimate goal is to identify the structural motifs that lead to both strong binding and a large static/dynamic quenching ratio. Such hosts will be ideal as photoinduced-electron-transfer catalysts. This grant from the Organic Dynamics Program supports the continuing work of Professor Christopher J. Abelt at the College of William and Mary. A pendant organic molecule, which can accept electrons upon ultraviolet light irradiation, will be bonded to a conically-shaped carbohydrate molecule. The carbohydrate molecule can act as a host to other molecules (guests) that can fit into this conically-shaped host. The guest molecules will be electron donors so that upon irradiation, an electron will be transferred from the guest to the pendant organic molecule. Since the volume of the host limits the field of guest molecules, selective electron transfer will occur.
