The Next Generation Organic Materials Oligoacenes, Heteroacenes and Cyclacenes

提出了一类全新的有机材料，即受保护的低聚芳烃和多聚芳烃。不像被广泛探索的共轭聚合物，这些不饱和大分子将成为电导体而不需要掺杂剂；它们将是第一个低茂烯，环茂烯可能会表现出更奇特的性质，比如在更高温度下的超导性。拟议的合成相对较短，因此将有大量材料可用于物理性质评估和器件（场效应管，LED，光电二极管等）的制造。有机电子材料刚刚以发光二极管（led）、光电二极管（塑料太阳能电池）和薄膜晶体管（TFTs）的形式进入商业工程的主流。与标准白炽灯相比，led产生的光更亮、更冷，在制造和使用方面对社会产生了巨大的影响。有机tft的制造也将比目前同等的硅基器件节能得多。这里提出的研究的另一个重要的社会效益将是这些基金支持的研究生和本科生的教育的显著进步。这些有机电子器件的发展将为我们未来的劳动力提供真正的跨学科教育基础。

A radically new class of organic materials, the protected oligoacenes and polyacenes are proposed. Unlike the much-explored conjugated polymers, these unsaturated macromolecules will be electrical conductors without the need of a dopant; they will be they first of the oligocenes, the cyclacenes may exhibit even more exotic properties, such as superconductivity at higher temperatures. The proposed syntheses are relatively short, so that large amounts of materials will be available for the evaluation of physical properties and device (FET, LED, photodiode, etc.) fabrication.Organic electronic materials have just entered the commercial engineering mainstream in the form of light-emitting diodes (LEDs), photodiodes (plastic solar cells) and thin film transistors (TFTs). The LEDs produce brighter and cooler light than standard incandescent lamps wand will have a large impact on society in terms of energy savings both in manufacturing and in use. The manufacture of organic TFTs will also be much more energy-efficient than the equivalent, current, silicon-based devices. Another important societal benefit of the research proposed here will be the considerably advance in the education of the graduate and undergraduate students supported by these funds. Development of these organic electronic devices will provide a truly interdisciplinary educational foundation for our future workforce.
