Two-Dimensional Macromolecular Architectures Constructed at Interfaces by Soft Solution Processes

Preparation of two-dimensional (2-D) materials prepared by the reactions at interfaces is introduced as soft solution processes. Two-dimensional supramolecular covalent adlayers or nanofilms with higher structures have been constructed from simple aromatic building block molecules under ambient conditions by thermodynamic self-assembly using the reversible Schiff-base coupling reaction. On-site recrystallization has been proposed as a straightforward method to produce large 2-D nanosheets of crystalline surface-anchored metal–organic coordination frameworks (SURMOF). The Cu(I)-catalyzed Huisgen click reaction at oil–water interfaces has been used to form various polymeric nanofilms including Janus type nanofilms at the interface.
