Significance

A core-shell-structured droplet with a 5-nanometer-sized fluorous phase interior is spontaneously and quantitatively self-assembled from 12 palladium ions and 24 ligands. The ligands are concisely synthesized from the Mitsunobu or the Williamson reaction to attach the perfluoroalkyl groups followed by Sonogashira coupling with 4-ethynylpyridine to fulfill the banana shape for the construction of the rigid shell. The droplets are able to selectively host perfluoroalkanes in their void space predicted by the per­fluoro tails of the ligands.
