Photocycloadditions to Fullerenes

9400666有机动力学方案的这笔赠款支持纽约大学的舒斯特教授、威尔逊教授和考特尼教授研究烯酮与富勒烯的光环加成反应的范围和机理。这些研究集中在分析富勒烯官能化的空间和电子影响，敏化和猝灭反应机理的实验，以及用光物理探针分析反应物之间的相互作用。用光敏电子转移反应和时间分辨光声量热法对富勒烯激发态和三重态1，4-双自由基进行了表征。在这个项目中，舒斯特、威尔逊和考特尼博士将进行富勒烯与各种烯酮的光环加成反应。他们的研究提供了一条使富勒烯功能化的新途径，并详细阐述了影响光化学反应途径的所有参数。他们对富勒烯的研究的意义是对重要的烯烃光环加成反应的深刻扩展。这项研究还将为富勒烯的光化学和光物理性质提供有价值的信息。

9400666 This grant from the Organic Dynamics Program supports the work of Professors Schuster, Wilson, and Courtney at New York University to study the scope and mechanism of photocycloadditions of fullerenes by enones. The studies focus on an analysis for steric and electronic influences of the fullerene functionalizations, sensitizing and quenching experiments to address the reaction mechanism, and analysis of the interaction between the reactants by photophysical probes. Characterization of fullerene excited states and triplet 1,4-biradicals is sought by photosensitized electron transfer reactions and time-resolved photoacoustic calorimetry. In this project Drs. Schuster, Wilson, and Courtney will conduct photocycloadditions of fullerenes by a variety of enones. Their research provides a novel route to functionalize fullerenes and addresses in detail all parameters that influence the photochemical reaction pathway. The significance of their studies on fullerenes is a profound expansion of the important photocycloadditions of olefins. This research will also provide much valued information on the photochemical and photophysical properties of fullerenes.
