The crystal structure of inorganic nanocrystals (NCs) is usually controlled by reaction temperature, according to their phase diagram. Chemical conversion of inorganic NCs via ion exchange reactions and galvanic replacement reactions can overcome the difficulties associated with controlling the size, shape, chemical composition and crystal structure in conventional syntheses. The retained shape of the parent-NCs in element replacement provides an opportunity to obtain non-equilibrium unique structures and even new structures of inorganic NCs, these final structures being known as “pseudomorphs”. Here, I present a new concept to manipulate crystal structures of NCs by using the shape of NCs as a tool, which has the potential to open an exciting new field of crystal engineering.
