Two-dimensional (2D) organic assemblies possess many intriguing properties such as planar structure, extended surface, flexibility and tailorability. The fabrication of 2D organic structures in a controlled manner is crucial to realize their potential functions and applications. In recent years, we have developed three methods to fabricate 2D organic assemblies through the rational design of building blocks. Firstly, hydrotropic anions will induce cationic bolaamphiphiles to form 2D assemblies, because such anions can insert their hydrophobic parts into the assemblies and weaken the electrostatic repulsion between adjacent headgroups. Secondly, the topology of supra-amphiphiles can be easily tuned because of the dynamic nature of non-covalent bonds, thus providing a facile approach for the fabrication of 2D assemblies. Thirdly, through molecular modification or introduction of new non-covalent bonds, we can lower the dimensionality of three-dimensional (3D) networks to form 2D assemblies. It is highly anticipated that these methods can be further applied for the preparation of functional 2D nano/micro materials for optoelectronics.
