Organic and inorganic materials are central to the function of new generations of optical and electronic devices that will play a role in future technologies. Solar cells rely on materials that absorb light and efficiently convert it to electricity, and displays for smart phones and laptops need materials that emit bright light efficiently. Conjugated materials are a class of organic polymers and oligomers that can be used for these applications and others. The properties of these materials can be enhanced by systematic modifications to the chemical structure, by appending groups which interact with the conjugated backbone in specific ways. This proposal explores the preparation of several new classes of modified conjugated materials, understanding the way they interact with light, and how they can be applied in solar cells, light emitting devices as well as in other applications. Specifically, materials in which conjugated units are linked with sulfur-containing groups will be studied. These new materials are anticipated to be useful in solar cells and light-emitting devices, as well as play a role in the development of printed security features for passports and currency. A second area of investigation will be the development of switchable conjugated materials, where the optoelectronic properties can be controlled by an external stimulus such as light, solvent or temperature. Conjugated materials in which the backbone contains both electron donor (Lewis basic) and electron acceptor (Lewis acidic) groups will be made and studied. The color and electronic properties of these compounds depends on how the two groups interact with each other, and possible applications in photoswitchable catalysts as well as cellular imaging will be explored. The fundamental knowledge that will be attained from this proposal will be used to further our understanding of these important materials and open new opportunities for exploiting their properties in a range of applications. The training of new scientists in this area of materials science and chemistry is an important outcome from the proposed program.

有机和无机材料对于新一代的光学和电子设备的功能至关重要，这些光学设备和电子设备将在未来的技术中发挥作用。 太阳能电池依赖于吸收光线并有效地将其转换为电能的材料，并显示出智能手机和笔记本电脑需要有效发光的材料。 共轭材料是一类有机聚合物和低聚物，可用于这些应用和其他应用。 通过对化学结构进行系统的修改，可以通过以特定方式与共轭主链相互作用来增强这些材料的性能。 该建议探讨了几类新的修改后的共轭材料的准备，了解它们与光的相互作用的方式以及如何应用于太阳能电池，发射器件以及其他应用中。 具体而言，将研究将共轭单元与含硫基团相关的材料。 预计这些新材料将在太阳能电池和发光设备中有用，并在护照和货币的印刷安全功能的开发中发挥作用。 第二个调查区域将是开发可切换的共轭材料，在该材料中，可以通过光，溶剂或温度等外部刺激来控制光电特性。 将制造和研究骨架含有电子供体（刘易斯基本）和电子受体（刘易斯酸性）组的共轭材料。 这些化合物的颜色和电子特性取决于两组如何相互作用，并且将探索可拍摄的催化剂以及细胞成像中的可能应用。 该提案将获得的基本知识将用于进一步了解我们对这些重要材料的理解，并为在一系列应用中开放其属性开辟了新的机会。 在这一材料科学和化学领域对新科学家的培训是拟议计划的重要结果。
