Phosphine‐initiated cation exchange is a well‐known inorganic chemistry reaction. In this work, different phosphines have been used to modulate the thermodynamic and kinetic parameters of the cation exchange reaction to synthesize complex semiconductor nanostructures. Besides preserving the original shape and size, phosphine‐initiated cation exchange reactions show potential to precisely tune the crystallinity and composition of metal/semiconductor core–shell and doped nanocrystals. Furthermore, systematic studies on different phosphines and on the elementary reaction mechanisms have been performed.
