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.

提出了一类全新的有机材料，保护的低聚并苯和多并苯。 不像许多探索的共轭聚合物，这些不饱和大分子将是电导体，而不需要掺杂剂;它们将是第一个低聚物，环并苯可能表现出更奇特的性质，例如在更高温度下的超导性。 所提出的合成相对较短，因此大量材料将可用于评估物理性能和器件（FET，LED，光电二极管等）。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（TFT）的形式进入商业工程主流。 LED产生比标准白炽灯更明亮和更冷的光，在制造和使用中的节能方面将对社会产生巨大影响。 有机TFT的制造也将比同等的当前硅基器件更节能。 这里提出的研究的另一个重要社会效益是这些基金支持的研究生和本科生的教育将取得显着进步。 这些有机电子设备的发展将为我们未来的劳动力提供一个真正的跨学科教育基础。
