Chemistry and physics of conjugated coordination nanosheets and two-dimensional conjugated polymers

共轭聚合物的光电特性已经提高到性能水平，现在可以在大面积电子，显示器，生物电子和光伏方面实现工业应用。然而，沿着传统共轭聚合物骨架的一维（1D）电荷传输特性仍然对可实现的载流子迁移率和电子性质施加了基本限制。在提议的项目中，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），它们最近通过配位化学可以合成，并有望克服一维聚合物的传统局限性。该项目的目的是研究这些新材料的基础化学和物理，特别是研究分子结构-电荷输运关系，探索其基本的，奇特的物理输运性质，并将其开发为能源和电子应用的高性能材料，特别是在热电，储能，发光和化学和生物传感器方面。该项目将在该领域的国际领先的化学和物理团队（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）之间建立一个紧密的跨学科网络。

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).
