The current interest in graphene, a naturally occurring two-dimensional polymer (2DP), highlights the necessity to produce other chemically different analogues. Until very recently there was no organic synthetic method available that would allow accessing a laterally infinite, one-monomer-unit thick, freestanding, unimolecular network with a defined internal periodicity. This talk will overview current efforts towards 2DPs with detailed discussion of our concepts, which rest upon carefully designed monomers, interfacial ordering, and both metal-complexation and light-induced polymerizations. In addition, we will report the synthesis of 2D random copolymers and a 2D block copolymer, which provide unprecedented structural diversity of 2DPs.
