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).

共轭聚合物的光电特性已提高到性能水平，现在可以在大区域电子，展示，生物电子和光伏的大区域应用中进行工业应用。但是，沿常规共轭聚合物的骨干的一维（1D）性质仍然对可实现的电荷载体迁移率和电子特性施加了基本限制。在拟议的项目中，我们旨在开发一种新型的二维（2D）共轭聚合物和协调纳米片（Conashs），这些聚合物（Conashs）最近已通过协调化学可以从合成中访问，并有望克服一维聚合物的传统限制。拟议项目的目的是研究这些新型材料的基本化学和物理，特别是研究了分子结构 - 电荷运输关系，探索其基本的，异国的物理运输特性，并将它们作为能量和电子应用的高性能材料发展，尤其是在热电学，储能存储，光发射，化学和化学和生物传感器中。该项目将在该领域的国际领先的化学和物理小组之间建立一个紧密的跨学科网络（Nishihara-东京大学，剑桥大学 - 坎布里奇的Sirringhaus-大学，冯 - 德累斯顿技术大学，Zhun/Zhang-中国科学院，北京）。
