Two-dimensional materials 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. For some of them it was proven that they are composed of topologically planar repeat units and they were therefore coined as synthetic two-dimensional polymers (2DP).

The presentation will focus on two examples of 2DPs synthesized in the single crystal and how their structure was analyzed including the edge groups. It will also briefly touch upon where these novel macromolecules could find applications.
