This research program is directed towards the development of new molecular and polymeric materials for use in optoelectronics, with a focus on efficient display and lighting technology. Artificial lighting currently accounts for 19% of global electricity consumption and is forecast to increase by 80% by 2030 unless the implementation of energy-efficient lighting substantially improves. Solid-state lighting based on organic light-emitting diodes (OLEDs) is a promising technology with the potential to address these concerns, yet the high cost and short lifetimes of OLED lighting panels remain significant barriers to the adoption of this technology in consumer lighting.******This proposal consists of three main research themes: 1) the synthesis of luminescent compounds for solid-state lighting; 2) the synthesis of functional brush polymers for electronic devices, and 3) the self-assembly of polymers into hierarchical nanostructured materials.******The first of these themes will focus on improving next-generation OLED displays by developing new materials with improved lifetimes and efficiencies. While OLED technology is now widespread in small consumer devices such as cellular phones and cameras, the lifetimes of the luminescent compounds inside the displays are not yet satisfactory for use in consumer lighting, where devices are normally left on for hours at a time. Our research will seek targeted improvements in this technology with the long-term goal of making consumer OLED lighting a reality.******The second research theme aims to address the high cost of fabrication of OLED lighting panels, which remains the main obstacle to the widespread adoption of OLED lighting. We will seek to develop both new polymeric materials and processing techniques for these next-generation displays. Our long-term goal is to bring OLED fabrication costs down in order to make this technology cost-competitive with traditional fluorescent lighting, such that substantial savings may be realized from both residential and commercial energy use. ******With these methods established, we will extend this chemistry to our third research theme, which aims to fabricate complex electronic structures on the nanoscale from newly created polymeric materials. These fundamental studies will examine problems at the interface of electronics and nanotechnology, such as the fabrication of macromolecular wires and diode-like structures by low-cost solution-phase processes. Such structures have potential applications in diverse fields such as electronics, nanomedicine, and environmental sensing, and our studies will seek to better understand how these nanostructures can be fabricated and controlled.

该研究计划旨在开发用于光电子学的新型分子和聚合物材料，重点是高效显示和照明技术。人工照明目前占全球电力消耗的 19%，预计到 2030 年将增加 80%，除非节能照明的实施得到大幅改善。基于有机发光二极管 (OLED) 的固态照明是一项很有前途的技术，有可能解决这些问题，但 OLED 照明面板的高成本和短使用寿命仍然是该技术在消费照明中采用的重大障碍。 ******该提案包括三个主要研究主题：1）用于固态照明的发光化合物的合成； 2) 用于电子设备的功能性刷状聚合物的合成，以及 3) 将聚合物自组装成分层纳米结构材料。*****这些主题中的第一个主题将侧重于通过开发新材料来改进下一代 OLED 显示器具有更长的使用寿命和更高的效率。虽然 OLED 技术现已广泛应用于手机和相机等小型消费设备中，但显示器内发光化合物的寿命对于消费照明的使用尚不令人满意，因为消费照明设备通常一次会打开几个小时。我们的研究将寻求对这项技术进行有针对性的改进，长期目标是使消费者 OLED 照明成为现实。******第二个研究主题旨在解决 OLED 照明面板的高制造成本问题，这仍然是主要问题OLED照明广泛采用的障碍。我们将寻求为这些下一代显示器开发新的聚合物材料和加工技术。我们的长期目标是降低 OLED 制造成本，以使该技术与传统荧光照明相比具有成本竞争力，从而可以大幅节省住宅和商业能源使用。 ******随着这些方法的建立，我们将把这种化学扩展到我们的第三个研究主题，该主题旨在用新创建的聚合物材料在纳米级上制造复杂的电子结构。这些基础研究将研究电子学和纳米技术接口的问题，例如通过低成本溶液相工艺制造高分子线和类二极管结构。这种结构在电子、纳米医学和环境传感等不同领域具有潜在的应用，我们的研究将寻求更好地了解如何制造和控制这些纳米结构。
