Here, we presented growth of thin films of two-dimensional covalent organic frameworks with an average domain size of ~2.83 μm^(2) and maximum domain size of up to ~26.19 μm^(2) using amphiphilic glycine derivatives on water surface. We envisage that this work will inspire the growth of a wide variety of organic two-dimensional materials with high crystallinity and boost their structure property investigations.展开更多
