Experimental Investigations of Fullerene Materials and Polymers. Optical Properties and Nonlinear Absorptive Applications

克莱姆森大学授予孙亚平的这一跨学科奖项得到了化学部的先进材料计划和材料研究部的固态化学计划的支持。研究的重点是设计和合成具有非线性光学性质的富勒烯材料和聚合物。我们将研究单官能化和多官能化C60衍生物以及含侧链富勒烯基团的聚合物的光物理和吸收性质，旨在开发分子内三重态能量供体-受体二元组作为强非线性吸收材料。具体地说，以(60)-富勒烯、卟啉和金属酞菁为供体，以β-胡萝卜素、二苯基十六碳辛烯及其衍生物为受体的二元化合物将被制备和评价。光限幅将是研究富勒烯聚合物材料的主要应用。这项研究将推动用于光学、电光、声光和光机械器件的材料的发展，如光限幅、存储和开关，并将增加我们对富勒烯材料和聚合物的化学和光物理的理解。

This interdisciplinary award to Ya-Ping Sun at Clemson University is supported by the Advanced Materials Program in the Chemistry Division and the Solid-State Chemistry Program in the Division of Materials Research. The focus of the research is the design and synthesis of fullerene materials and polymers with nonlinear optical properties. The photophysical and absorptive properties of mono- and polyfunctionalized C60 derivatives, and polymers with pendant fullerene groups will be investigated, directed towards developing intramolecular triplet energy donor-acceptor dyads as strong nonlinear absorbers. Specifically, dyads employing (60)-fullerene, porphyrins, and metallophthalocyanines as the donors and beta-carotene, diphenylhexadecaoctaenes and their derivatives as acceptors will be prepared and evaluated. Optical limiting will be the primary application investigated for the polymeric fullerene materials. This research will advance the development of materials for optical, electro-optical, acousto-optical and optomechanical devices for applications such as optical limiting, storage, and switching and will increase our understanding of the chemistry and photophysics of fullerene materials and polymers.
