Two-dimensional self-assembly of amphiphilic porphyrins on a dynamically shrinking droplet surface

Unique self-assembled structures can be selectively created depending on the initial stage of the droplet. By using the droplet as a self-assembly field, we can select an appropriate self-assembly pathway by merely changing the initial state of the droplet.
