Synthesis of 2D polymers — •Dieter A. Schlüter — ETH Zurich, Department of Materials, Zurich, Switzerland

Two-dimensional materials (2DM) are sheet-like entities and of great interest for their manifold properties. Famous representatives are graphene, boronitride or molybdenum disulfide. 2DMs are often provided by nature or are obtained under harsh conditions. Such conditions exclude the synthetic arsenal of organic chemistry to be used for rational sheet creation, sheet structure variation and sheet engineering on a molecular level. Recently it was shown that covalent monolayer sheets can be easily accessed at room temperature by genuine two-dimensional polymerizations of organic monomers applying simple protocols. They include spreading of monomers at an air/water interface or crystallizing them into layered single crystals followed by metal complexation or light-induced growth reactions. These growth reactions result in macroscopic sheets of considerable mechanical strength. Some of them are composed of planar repeat units over their entire expanse and were introduced as synthetic two-dimensional polymers (2DP). Particularly in view of the ease of synthesis and the high level of structure control during polymerization we consider this the onset of a major research activity with serious applications at the horizon. Synthetic sheets and 2DPs will increasingly complement graphene and other known sheets. The contribution addresses strategic, synthetic and analytical issues and provides a view into future.
