Tuning the Supramolecular Structure and Properties of Polydiacetylenes with Charge-Transfer Interactions

化学系的先进材料计划将这一奖项授予福尔曼大学，以从功能化的二乙炔制备固态电荷转移络合物。凭借这一奖项，福尔曼大学的蒂莫西·汉克斯教授和克莱姆森大学的威廉·彭宁顿教授将从聚合物材料的“口袋”或“腔”中制备三种类型的聚合物材料-晶体和微晶粉末，以及无定形薄膜-从带有夹杂受体的供体二乙炔分子衍生的主体-化合物-有机碘。这些聚合物通过热解或溶剂萃取去除包合物后，将制备出纳米孔沸石类材料。许多给体分子不仅可以光聚合，还可以为受体分子提供不同大小和形状的空穴，这些研究可能会导致新型的多孔有机固体具有可调的光学、电学和化学性质。本研究将制备的类沸石纳米孔材料有望具有可调的光学、电学和化学性质。这个项目在一个以本科生为主的机构，有一个活跃的本科生和高中生研究计划，将提供另外的研究和教育机会，在材料合成和表征。

The Advanced Materials Program in the Division of Chemistry makes this award to Furman University to prepare solid-state charge-transfer complexes from functionalized diacetylenes. With this award, Professors Timothy Hanks at Furman University and William Pennington at Clemson University will prepare three types of polymeric materials - crystalline and microcrystalline powders, and amorphous thin films - from hosts derived from donor diacetylene molecules with attached inclusion acceptor-compounds - organo-iodides - in a 'pocket' or 'cavity' of the polymeric material. Nanoporous zeolite type materials will be prepared from these polymers after removal of the inclusion compounds by thermolysis or solvent extraction. A number of donor molecules, which not only photopolymerize, but also provide cavities of different sizes and shapes for acceptor molecules, will be synthesized and characterized, and these studies may result in new classes of porous organic solids with tunable optical, electronic and chemical properties.The zeolite-like nanoporous materials that will be prepared in this study are expected to have tunable optical, electronic and chemical properties. This project at a primarily undergraduate institution, which has an active research program with undergraduate and high school students, will provide, in addition, research and educational opportunities in material synthesis and characterization.
