Conjugated and redox active polymers and hybrid materials

这份申请描述了我们研究计划的三个方面。第一部分概述了新的合成方法和共轭聚合物的设计。第二个将讨论结合共轭有机材料和二维钙钛矿的项目。最后一节将描述我们在设计用于储能的聚合物方面的持续努力。这三个领域描述了一个以材料化学为重点的项目的连续体，在过去的6年里，有58名学员参与了该项目，并希望在未来取得更大的成就。首先，我讨论了我们最近在控制合成共轭聚合物方面的进展。在过去的2年里，我们展示了新的反应方法，利用化学计量试剂和温度循环以均匀的方式生产单分散（无分散）低聚物。我们的短期目标是将这种方法扩展到新的单体类型，包括具有挑战性的重原子变体。从长远来看，我们将利用这种方法开发复杂共轭高寡聚物的序列控制。我们将研究这些聚合物的氧化还原掺杂及其自组装行为。我们还计划与其他团队合作，准备研究这些独特的定义良好的聚合物半导体的超快动力学和热电性能。其次，我揭示了在二维有机-无机钙钛矿领域的一些非常新的和不同的工作。在这里，我们正在构建共轭分子系统来编程混合固体中的组装和光电子特性。特别是，我们正在使用共轭分子桥方法将二维材料堆叠起来，并提供供体-受体偶极子来控制整个固体的光电特性。从长远来看，我们计划开发各种由这些材料组成的设备，包括led，激光器，光电探测器和电光转换器。最后，重点介绍了聚合物在储能器件中的设计、合成和测试。毫无疑问，在未来10年里，世界将需要大量的可充电电池。除了电动汽车和电网规模的存储，在可预见的未来，许多其他用途，如电动航空、船舶和集成电子产品，将出现和/或迅速增长。我描述了两个新的领域。第一个重点是聚合物基阴极。第二个重点是氧化还原活性小分子的独特设计，旨在实现高稳定性。总的来说，这些项目有望创造一个丰富的培养环境，让学生和博士后同事可以相互学习，分享想法，为彼此的项目做出贡献，并享受他们在我们小组的时间。我还描述了我的团队发起的许多计划，以增加我们对公平、多样性和包容性的贡献。这包括一个关于EDI的团体政策，它宣称包容是我们科学目标的一个同等重要的原则。

This application describes three facets of our research program. The first outlines new synthetic methods and designs of conjugated polymers. The second will discuss projects that merge conjugated organic materials and 2D perovskites. The final section will describe our continuing efforts in the design of polymers for energy storage. These three areas describe a continuum of a program focused on materials chemistry that has involved 58 trainees in the last 6 years, and the ambition to be even more productive in the future. First, I discuss our recent progress in the controlled synthesis of conjugated polymers. In the last 2 years, we have demonstrated new reaction methodologies to produce mono disperse (no dispersity) oligomers in a homogeneous manner using stoichiometric reagents and temperature cycling. Our short-term goals are to expand this method for new monomer types, including the challenging heavy atom variants. In the longer term, we will utilize this method to develop the sequence control of complex conjugated high oligomers. We will study the redox doping of these polymers as well as their self- assembly behaviour. We also plan to collaborate with other groups that are poised to study the ultrafast dynamics and thermoelectric performance of these unique well-defined polymer semiconductors. Second, I disclose some very new and different work in the area of 2D organic-inorganic perovskites. Here, we are building conjugated molecular systems to program the assembly and optoelectronic properties in hybrid solids. In particular, we are using a conjugated molecular bridge approach to wire up the stacks of 2D materials and also provide donor-acceptor dipoles to govern the optoelectronic properties of the entire solid. In the longer term we plan to develop a variety of devices comprising these materials including LEDs, lasers, photodetectors and electrooptic converters. Finally, I focus on the design, synthesis and testing of polymers in energy storage devices. There is no question that the world will need enormous numbers of rechargeable batteries over the next 10 years. Aside from electric vehicles and grid-scale storage, many other uses such as electric aviation, watercrafts, and integrated electronics will emerge and/or grow rapidly during the foreseeable future. I describe two new areas. The first focuses on polymer-based cathodes. The second focuses on unique designs for redox active small molecules, designed for high stability. Overall, these projects are expected create a rich training environment where students and postdoctoral colleagues can learn from one another, share ideas, contribute to each other's projects and enjoy their time in our group. I also delineate many of the plans that my group has initiated to increase our contributions to equity, diversity and inclusion. This includes a group policy on EDI that professes inclusion as an equally important principal to our science goals.
