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

化学系的先进材料计划将此奖项授予弗曼大学，以从官能化的二乙炔制备固态电荷转移复合物。 凭借这一奖项，弗曼大学的蒂莫西·汉克斯教授和克莱姆森大学的威廉·彭宁顿教授将在聚合物材料的“口袋”或“空腔”中制备三种类型的聚合物材料--结晶和微晶粉末，以及非晶薄膜--从供体二乙炔分子衍生的主体中，与附加的包含受体化合物-有机碘化物。在通过热处理或溶剂萃取除去包合化合物之后，将从这些聚合物制备纳米多孔沸石型材料。一些供体分子，不仅光聚合，但也提供了不同的大小和形状的受体分子的空腔，将被合成和表征，这些研究可能会导致新的类别的多孔有机固体具有可调的光学，电子和化学性质。沸石类纳米多孔材料，将在本研究中被期望制备具有可调的光学，电子和化学性质。该项目主要在本科院校进行，该院校与本科生和高中生有着积极的研究计划，此外，该项目还将提供材料合成和表征方面的研究和教育机会。

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.
