项目摘要
With the support of the Macromolecular, Supramolecular and Nanochemistry program in the Division of Chemistry, Professors Howard E. Katz and Paulette Clancy of the Johns Hopkins University are developing small organic molecules for use in doping of conjugated polymers. Conjugated polymers are carbon-based macromolecules that contain long chains consisting of alternating double and single bonds. When the double bond arrangements are changed by removing or adding electrons, positive and negative charges are created in the polymers that enable them to conduct electricity similarly to metals such as copper. Currently, conjugated polymers are the most important class of materials used for optoelectronic devices such as LED (light-emitting diode) screens in mobile devices and computers; also being used to protect such electronic components from outside electrical interference. In this research, systematic studies using a combination of experimental and computational approaches will closely examine the mechanism of electron transfer in these polymeric systems, a mechanism for which many details are still not known. Increased understanding of such systems has the potential to lead to novel conjugated materials with tunable electronic properties of relevance to flexible electronics and power devices. The education and outreach activities of this project will focus on the engineering innovation program at Johns Hopkins University targeting low-income Baltimore City participants. A boot camp on coding will be offered to middle schoolers with the goal of improving the programming skills of future STEM (Science, Technology, Engineering and Math) scientists, with the particular goal of reaching women and members of underrepresented groups.This research is targeting a series of thiophene-based molecules and oligomers for use in doping of conjugated polymers. The proposed theoretical and experimental studies are designed to test the hypothesis that the free energy change from (a) difference in hole/electron affinities, (b) work of charge separation, and (c) delocalization/distribution entropy between neutral conjugated polymers and covalent ion-adducts will lead to charge transfer and electrical conductivity. Thiophene-based conjugated molecules and oligomers for adduct formation studies will be selected with a range of hardness/softness and to favor paired-electron, covalent bond formation (as opposed to electron transfer interactions) in aprotic solvents to enable testing of whether the covalent adducts ultimately serve as electron transfer agents of conjugated polymers. Extensive spectroscopic and electrochemical characterization methods are to be used to gain a deeper understanding of the doping mechanism and how structural changes affect doping levels, solid-state structures, conductivity, and the Seebeck coefficient. The results associated with this research have the potential to lead to more reliable doping strategies in conjugated polymer- a key challenge for further development of organic bioelectronics and flexible conductors.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.
在化学系大分子、超分子和纳米化学项目的支持下,约翰霍普金斯大学的Howard E.Katz教授和Paulette Clancy教授正在开发用于共轭聚合物掺杂的小有机分子。共轭聚合物是基于碳基的大分子,含有由交替的双键和单键组成的长链。当通过移除或添加电子来改变双键排列时,聚合物中会产生正电荷和负电荷,使它们能够像铜等金属一样导电。目前,共轭聚合物是用于移动设备和计算机中的LED(发光二极管)屏幕等光电设备的最重要的一类材料;也被用来保护这些电子元件免受外部电子干扰。在这项研究中,采用实验和计算相结合的方法进行的系统研究将仔细检查这些聚合物体系中的电子转移机制,这一机制的许多细节仍不清楚。对这类体系的了解的增加有可能导致具有与柔性电子和电力设备相关的可调电子性能的新型共轭材料。该项目的教育和外展活动将侧重于约翰·霍普金斯大学针对巴尔的摩市低收入参与者的工程创新计划。将为中学生提供编码新兵训练营,目标是提高未来STEM(科学、技术、工程和数学)科学家的编程技能,特别是接触到女性和代表不足的群体的成员。这项研究的目标是一系列用于掺杂共轭聚合物的噻吩基分子和低聚物。所提出的理论和实验研究旨在验证这样的假设:(A)空穴/电子亲和势的差异,(B)电荷分离功,(C)中性共轭聚合物和共价离子加合物之间的离域/分布熵将导致电荷转移和导电性。用于加合物形成研究的基于噻吩基的共轭分子和低聚物的选择具有一定的硬度/柔软性,并有利于在非质子溶剂中形成成对电子的共价键(与电子转移相互作用相反),以便能够测试共价加合物是否最终用作共轭聚合物的电子转移剂。广泛的光谱和电化学表征方法将被用来更深入地了解掺杂机制以及结构变化如何影响掺杂水平、固态结构、电导率和塞贝克系数。与这项研究相关的结果有可能导致在共轭聚合物中使用更可靠的掺杂策略-这是进一步发展有机生物电子和柔性导体的关键挑战。该奖项反映了NSF的法定使命,并通过使用基金会的智力优势和更广泛的影响审查标准进行评估,被认为值得支持。
