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).
