中文摘要
化学部的先进材料计划将该奖项授予北达科他州州立大学法戈,以合成和表征由过渡金属和聚噻吩并[3,4-B]吡嗪及其烷基化衍生物制备的金属-聚合物杂化物。 这些复合材料有望具有过渡金属配合物的光电性能和有机聚合物的光电性能。 由于金属中心将直接结合到聚合物主链上,除了更强的金属-聚合物电子耦合之外,还将消除不期望的空间相互作用。这种不使用共聚体系制备复合材料的方法将具有用于生产良好有序的金属化聚合物的合成控制,这反过来将保留共轭聚合物的期望方面,同时允许金属中心用作电开关或光敏开关以调节聚合物性质。 有序杂金属共轭聚合物也将被合成,以确定这些杂化系统的结构-性能关系,并将评估它们在导电,光导和非线性光学材料中的潜在应用。 职业发展计划将化学史纳入化学课程,包括本科和研究生课程,包括研讨会和基于网络的化学史展示。 这些计划也将提供给北达科他州的高中科学教师,作为一种方式,让他们包括这种材料在他们的课程。聚合物-金属复合材料将准备从导电聚合物和过渡金属。 由于金属中心将直接结合到这些材料中的聚合物主链上,因此这些有序和定向的杂化物有望提供增强的电子和光学性质。 该项目的长期目标将是制备用于多维阵列的异金属,多维和共轭聚合物材料,用于信息存储的超分子芯片的潜在应用。 一个新的课程,教化学史将推出在研究生和本科水平。 高中科学教师也将有机会参加化学史课程。
英文摘要
The Advanced Materials Program in the Division of Chemistry makes this award to North Dakota State University Fargo to synthesize and characterize metal-polymer hybrids prepared from transition metals and polythieno[3,4-b]pyrazine and its alkylated derivatives. These composite materials are expected to have the electro- and photochemical properties of transition metal complexes with the electronic and optical properties of the organic polymer. Since metal centers will be bound directly to the polymer backbone, undesirable steric interactions will be eliminated in addition to stronger metal-polymer electronic coupling. This methodology to prepare composites without the use of copolymeric systems will have synthetic control for the production of well-ordered metallated polymers, which in turn will retain the desirable aspects of the conjugated polymer while allowing the metal centers to serve as electro- or photosensitive switches to modulate the polymer properties. Ordered heterometallic conjugated polymers will also be synthesized to determine structure-property relationships of these hybrid systems, and they will be evaluated for their potential applications in conducting, photo-conducting, and nonlinear optical materials. The Career Development Plan will incorporate History of Chemistry into the chemistry curriculum both at the undergraduate and graduate level courses with credit including seminars and web-based chemical history displays. These programs will also be offered to North Dakota high school science teachers as a way to allow them to include this material in their curriculum.Polymer-metal composites will be prepared from conducting polymers and transition metals. Since the metal centers will be bound directly to the polymer backbone in these materials, these well-ordered and oriented hybrids are expected to provide enhanced electronic and optical properties. Long-term goals of the project will be to prepare heterometallic, multidimensional and conjugated polymer materials for multi-dimensional arrays for potential applications in supramolecular chips for information storage. A new curriculum to teach History of Chemistry will be introduced at both graduate and undergraduate levels. High school science teachers will also be provided opportunities to take the course in History of Chemistry.
