The Nobel prize winning discovery that organic polymers can act as semiconductors has led to a worldwide academic and industrial research effort focused on the development of these materials and their utilization in electronic devices including lighting, transistors, and solar cells. Compared to traditional inorganic materials, organics offer the ability to be processed from solution onto light weight and flexible substrates. Specifically, such 'conductive inks' can be printed via roll to roll fabrication techniques, similar to that of newspaper printing, making these technologies extremely cost effective.Materials innovation represents a critical aspect for the progression of organic electronics. This proposal is based off the very recent discovery that well-defined small molecules can form desirable structures through processing from solution. Until now, solution processing has required high molecular weight polymers which suffer from complex supramolecular structures, whereas low molecular weight species have required deposition by vacuum sublimation. Combining the virtue of well-defined molecular synthesis with those of solution processing provides a very important new opportunity for the advancement of organic electronics. The proposed research is focused on the development of new soluble small molecules for use in organic solar cells. Organic solar cells are light, flexible, semi-transparent, and more environmentally-friendly than traditional inorganic based cells. These properties open up possibilities for exciting new applications, including building integration and portable solar power. Successful completion of this project will produce highly trained personnel with a broad education in chemistry and materials science, and scientifically lead to improvements in the performance and reliability of organic solar cells, bringing this technology one step closer to wide spread commercialization.

诺贝尔奖得主发现有机聚合物可以作为半导体，这一发现引发了全球学术界和工业界的研究努力，重点是开发这些材料，并将其应用于电子设备，包括照明、晶体管和太阳能电池。与传统的无机材料相比，有机材料提供了从溶液到轻质和柔性基板的加工能力。具体来说，这种“导电油墨”可以通过卷对卷制造技术进行印刷，类似于报纸印刷，使这些技术具有极高的成本效益。材料创新是有机电子学发展的一个重要方面。这一建议是基于最近的发现，即定义良好的小分子可以通过处理溶液形成理想的结构。到目前为止，溶液处理需要高分子量的聚合物，这些聚合物具有复杂的超分子结构，而低分子量的聚合物则需要真空升华沉积。分子合成的良好定义与溶液处理的优点相结合，为有机电子学的发展提供了非常重要的新机遇。提出的研究重点是开发用于有机太阳能电池的新型可溶性小分子。有机太阳能电池轻、柔韧、半透明，比传统的无机基电池更环保。这些特性为令人兴奋的新应用开辟了可能性，包括建筑集成和便携式太阳能。该项目的成功完成将培养出受过广泛化学和材料科学教育的高素质人才，并在科学上改善有机太阳能电池的性能和可靠性，使这项技术更接近广泛的商业化。
