A MRSEC team has reliably synthesized two-dimensional polymers (2DP) with wafer-scale homogeneity in the ultimate limit of monolayer thickness using a general and scalable growth method called laminar assembly polymerization.
The lattice structures and optical properties of these single-molecule-thick, freestanding crystalline films are directly controlled by altering the molecular monomers and polymerization chemistries.
The 2D polymers are fully compatible with existing large-scale patterning and integration methods, which we successfully demonstrate by producing arrays of hybrid heterostructuresand superlatticesbuilt layer by layer using 2D polymers and 2D atomic crystals.
