项目摘要

In this project funded by the Macromolecular, Supramolecular and Nanochemistry Program in the Division of Chemistry, Dr. Genevieve Sauve of the Department of Chemistry at Case Western Reserve University is developing new synthetic approaches for making semiconducting organic materials by incorporating metals. Organic semiconductors are solids whose building blocks mainly consist of carbon and hydrogen atoms, and at times nitrogen, sulfur and oxygen. Each carbon atom in these materials is bonded to other carbons not only through single bonds, but also with special bonds called pi-bonds. The alternating pi-bonds enables the molecules (polymers) to conduct electrons. Just like traditional semiconductors made with silicon, these materials can become conductive when one applies a voltage (like in transistors) or shines light on them (like in photovoltaic cells). The big advantage of organic semiconductors is that they can be printed, just like ink, enabling inexpensive and scalable production of electronic devices. In addition, organic semiconductors are plastic-like, producing flexible and lightweight devices that could be used where rigid and heavy silicon-based devices cannot. However, devices based on organic semiconductors tend to have lower performance than devices based on traditional semiconductors. In this research, highly innovative and creative chemical reactions are used to improve the performance of organic semiconductors by using metals. The purpose of adding metals to these materials is to provide additional control over not only electrical conductivity, but also crystallinity and solution processing properties. Materials prepared in this project are expected to impact the printable electronic industry, providing portable devices and alternative ways to convert solar energy to high value electricity. Students associated with this project are exposed to interdisciplinary research and are prepared to be next generation of scientists. Education and outreach activities posted on YouTube target high school students and underrepresented groups as the videos demonstration the real-life applications of pi-conjugated materials.Solution-processable organic semiconductors are poised to revolutionize the electronic and printing industries, but to achieve the most desirable properties, new creative approaches and synthetic strategies are required. Conventional approaches to organic semiconductor design typically rely on purely planar pi-conjugated systems whose opto-electronic properties are tuned with the nature of the chemical backbone, functional groups and side-chains. To access new functionalities, this project turns to hybrid organic/inorganic coordination compounds, where coordination with main group or transition metals provides an additional tool to tune the properties of pi-conjugated systems, such as molecular shape, crystallinity and opto-electronic properties. This research exploits azadipyrromethene complexes as a versatile platform for development of the next generation of solution-processable hybrid semiconductors. The research has the potential to impact the field of pi-conjugated systems, dyes with visible NIR absorption and organic electronics.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.

在该项目由化学系的大分子，超分子和纳米化学计划资助的项目中，凯斯西部储备大学化学系的Genevieve Sauve博士正在开发新的合成方法，用于通过合并金属来制造半导体有机材料。有机半导体是固体，其基础主要由碳和氢原子组成，有时以及氮，硫和氧气。这些材料中的每个碳原子不仅通过单键键粘合到其他碳，而且还具有称为pi键的特殊键。交替的PI键使分子（聚合物）能够传导电子。就像传统的半导体用硅制成的一样，当施加电压（例如在晶体管中）或在其上亮（例如在光伏电池中）时，这些材料也会变成导电。有机半导体的最大优点是可以像墨水一样印刷它们，从而实现电子设备的便宜且可扩展的生产。此外，有机半导体是塑料状的，可以在刚性和重型硅的设备无法使用的地方生产柔性和轻巧的设备。但是，基于有机半导体的设备的性能往往比基于传统半导体的设备低。在这项研究中，使用高度创新和创造性的化学反应用于通过使用金属来提高有机半导体的性能。将金属添加到这些材料中的目的是对不仅电导率，还提供结晶度和溶液处理性能提供额外的控制。预计该项目中准备的材料将影响可打印的电子行业，提供便携式设备和替代方法，以将太阳能转换为高价值电力。与该项目相关的学生接触了跨学科研究，并准备成为下一代科学家。 YouTube上发布的教育和外展活动针对高中生和代表性不足的群体，展示了PI偶联的材料的真实应用。Sultolution-Soluce-Procorporpoperspopleconpoperpoperpoperpoperpopercoperpoperpo的有机半导体有望革新电子和印刷行业，但要实现最可取的特性，新的创造性方法和合成的策略。有机半导体设计的常规方法通常依赖于纯平面Pi偶联的系统，其光电极特性以化学骨架，官能团和侧链的性质调节。为了访问新功能，该项目转向混合有机/无机协调化合物，其中与主组或过渡金属的协调提供了一种额外的工具来调整PI共偶联系统的性质，例如分子形状，结晶度和Opto-Electronic属性。这项研究利用了芳香甲甲苯络合物，作为开发下一代溶液处理混合动力半导体的多功能平台。这项研究有可能影响PI结合系统，具有可见性NIR吸收和有机电子产品的染料。该奖项反映了NSF的法定任务，并被认为是值得通过基金会的智力优点和更广泛影响的评估来评估的支持标准。
