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.

该跨学科奖项授予克莱姆森大学的孙亚萍，由化学学部的先进材料项目和材料研究学部的固态化学项目支持。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。研究了单功能化和多功能化C60衍生物的光物理和吸收特性，以及具有垂坠富勒烯基团的聚合物，旨在开发分子内三重态能量供体-受体二元体作为强非线性吸收剂。具体来说，以(60)-富勒烯、卟啉和金属酞菁为供体，β -胡萝卜素、二苯基十六烷基辛烯及其衍生物为受体的二偶体将被制备和评价。光限制将是高分子富勒烯材料的主要应用。这项研究将促进光学、电光、声光和光机械器件材料的发展，用于诸如光限制、存储和开关等应用，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。
