The optoelectronic properties of conjugated polymers have improved to levels of performance that now enable industrial applications in large-area electronics, displays, bioelectronics and photovoltaics. However, the one-dimensional (1D) nature of charge transport along the backbone of a conventional conjugated polymer still imposes fundamental limits on the achievable charge carrier mobilities and electronic properties. In the proposed project we aim to develop a novel class of 2-dimensional (2D) conjugated polymers and coordination nanosheets (CONASHs), which have recently become synthetically accessible through coordination chemistry and promise to overcome the traditional limitations of 1D polymers. The aim of the proposed project is to investigate the fundamental chemistry and physics of these novel materials, in particular investigate the molecular structure - charge transport relationships, explore their fundamental, exotic physical transport properties and develop them as high performance materials for energy and electronic applications, in particular in thermoelectrics, energy storage, light-emission and chemical and biological sensors. The project will establish a close, interdisciplinary network between internationally leading chemistry and physics groups in this field (Nishihara - University of Tokyo, Sirringhaus -University of Cambridge, Feng - Technical University of Dresden, Zhu/Zhang - Chinese Academy of Sciences, Beijing).

共轭聚合物的光电性能已经提高到现在能够在大面积电子学、显示器、生物电子学和光电子学中实现工业应用的性能水平。然而，电荷沿常规共轭聚合物的主链沿着传输的一维（1D）性质仍然对可实现的电荷载流子迁移率和电子性质施加基本限制。在拟议的项目中，我们的目标是开发一类新的二维（2D）共轭聚合物和配位纳米片（CONASHS），最近已成为通过配位化学合成访问，并承诺克服传统的限制一维聚合物。该项目的目的是研究这些新型材料的基本化学和物理学，特别是研究分子结构-电荷传输关系，探索其基本的，奇异的物理传输特性，并将其开发为能源和电子应用的高性能材料，特别是热电，储能，发光以及化学和生物传感器。该项目将在这一领域的国际领先化学和物理团体之间建立一个密切的跨学科网络（西原-东京大学，Sirringhaus -剑桥大学，冯-德累斯顿工业大学，朱/张-中国科学院，北京）。
