Non-technical DescriptionOrganic semiconductors (OSCs) are a class of materials that combine the electronic properties of semiconductors with the chemical and mechanical properties of organic compounds, such as polymers. OSCs have unique characteristics and offer fundamentally new approaches to harvest energy, making them increasingly interesting for a range of emerging technology applications, including sustainable energy, electronics and biomedicine. However, limitations in the ability to predict, synthesize and control OSCs and to understand the complexities of matter across a range of scales hamper their broad application. This project aims to overcome these barriers by generating the knowledge needed to extend the utility of OSCs into the infrared region (IR) and control electronic correlations in organic and hybrid systems. The research includes the development of new materials and systems that have unique electronic, and optical properties for present and future science and engineering challenges such as sustainable energy, electronics, and biomedicine. Applications include solar cell devices, hybrid electronics, bioimaging and biosensing. A new interdisciplinary material research Center for Emerging Molecular Optoelectronics (CEMOs) will be formed. Through this Center, the project will share resources and leverage partnerships among Mississippi institutions of higher learning, national laboratories, and industry as well as establish national and international collaborations to strengthen the research capacity and to build and train an inclusive workforce in optoelectronics.Technical DescriptionThe processes of capturing energy from IR light and controlling electronic correlations in organic and hybrid systems has profound implications for next generation energy technologies and for developing materials with novel optoelectronic functionalities. CEMOs will develop theoretical and experimental tools, materials, and techniques to overcome fundamental limitations of OSCs. Theoretical models will be developed to establish design rules for guiding experiments, materials development, predicting properties, and tailoring morphology to understand complex contributions affecting optical and electrical processes. Systematic and iterative research approaches in theory and experiments will provide understanding of how photophysical, electronic, structural, and morphological properties relate to elementary excitations, dynamic processes, and electronic correlations within complex materials systems. The project team will synthesize new materials capable of optical to electrical signal transduction of longer wavelength light and develop new engineering routes to meet technologically challenging IR applications, including biomedicine and biosensing. The Center's education, outreach, and workforce development efforts will serve to support the development of a qualified STEM workforce in Mississippi, including new faculty hires and student engagement that will increase diversity at all levels. CEMOs will facilitate the development of research capabilities, infrastructure, and education opportunities in the areas of energy, advanced manufacturing, and health in alignment with the state's Science and Technology priorities.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.

非技术描述有机半导体（OSCs）是一类结合了半导体的电子特性与有机化合物（如聚合物）的化学和机械特性的材料。OSCs具有独特的特性，并提供了全新的能量收集方法，使其越来越受到包括可持续能源、电子和生物医学在内的一系列新兴技术应用的关注。然而，在预测、合成和控制osc的能力以及在一系列尺度上理解物质复杂性方面的局限性阻碍了它们的广泛应用。该项目旨在通过产生将OSCs的应用扩展到红外区域（IR）和控制有机和混合系统中的电子相关性所需的知识来克服这些障碍。该研究包括开发具有独特电子和光学特性的新材料和系统，以应对当前和未来的科学和工程挑战，如可持续能源、电子和生物医学。应用包括太阳能电池装置、混合电子、生物成像和生物传感。新组建新兴分子光电子学跨学科材料研究中心。通过该中心，该项目将在密西西比州高等院校、国家实验室和工业界之间共享资源和利用伙伴关系，并建立国内和国际合作，以加强研究能力，建立和培训一支包容性的光电子劳动力队伍。技术描述从红外光捕获能量和控制有机和混合系统中的电子相关性的过程对下一代能源技术和开发具有新型光电功能的材料具有深远的影响。cemo将开发理论和实验工具、材料和技术来克服osc的基本限制。将发展理论模型，建立设计规则，指导实验、材料开发、预测性能和裁剪形态，以了解影响光学和电学过程的复杂贡献。系统和迭代的理论和实验研究方法将提供对复杂材料系统中的光物理，电子，结构和形态特性如何与基本激发，动态过程和电子相关性相关的理解。该项目团队将合成能够将较长波长的光转换为电信号的新材料，并开发新的工程路线，以满足技术上具有挑战性的红外应用，包括生物医学和生物传感。该中心的教育、推广和劳动力发展工作将有助于支持密西西比州合格STEM劳动力的发展，包括新教师招聘和学生参与，这将增加各个层面的多样性。cemo将促进能源、先进制造业和健康领域的研究能力、基础设施和教育机会的发展，与国家的科学和技术优先事项保持一致。该奖项反映了美国国家科学基金会的法定使命，并通过使用基金会的知识价值和更广泛的影响审查标准进行评估，被认为值得支持。
