Novel pi-conjugated materials for emitting devices

共轭有机材料是有机发光二极管和分子导线中应用的理想目标，具有光学、发光和导电性能。取决于结构，表现出这些性质的共轭有机材料可用于柔性光显示器和低功耗产品中的应用，包括廉价的场效应晶体管。然而，共轭有机材料的合成并不是一个简单的过程。常规合成方法需要多个步骤和具有挑战性的纯化以分离所需的缀合材料。近年来，我们的实验室开发了新的方法，用于有效合成用于固有导电聚合物（ICP）的单体。我们提出了一种替代的合成路线，以获得新的共聚单体和功能聚合物作为有机发光二极管的应用。我们还发现了用于缩合化学的温和条件，以方便地制备新型共轭聚甲亚胺，其预期表现出比常规共轭聚合物更好的物理性质范围。随着新型共聚单体的有效获得，我们现在建议在温和的缩合过程中使用这些结构单元来制备一系列独特的共轭材料。目标共轭有机材料将具有针对光学和电子器件中的应用而调整的物理性质。

Conjugated organic materials are desired targets for applications in organic light emitting diodes and molecular wires for possessing optical, emitting, and conducting properties. Contingent on structure, conjugated organic materials which exhibit these properties can be used for applications in flexible light displays and low power consumption products, including inexpensive field effect transitors. The synthesis of conjugated organic materials has, however, not been a simple process. Conventional synthetic methods have required multiple steps and challenging purifications to isolate the desired conjugated materials. In recent years, our laboratories have developed new methodologies for the efficient synthesis of monomers used for inherently conducting polymers (ICPs). We present an alternative synthetic route to access novel comonomers and functional polymers for application as organic light emitting diodes. We have also found mild conditions for condensation chemistry to conveniently make novel conjugated polyazomethines, which are expected to exhibit a better range of physical properties than conventional conjugated polymers. With effective access to novel comonomers, we now propose to employ these building blocks in the mild condensation process to prepare a unique series of conjugated materials. The targeted conjugated organic materials will possess physical properties that are tuned for applications in optical and electronic devices.
