Thus far, reports about the transformations for dynamic crystals of supramolecular coordination systems mainly include single‐crystal‐to‐single‐crystal reactions, and solvent‐mediated processes. This Concept focuses on the mechanisms for solvent‐mediated structural transformations of dynamic crystals, which can be classified into two categories, that is, core‐on‐shell and core‐to‐core. The core‐on‐shell mechanism means that the core of the new crystal is generated from the shell of original crystal, being concomitant with the dissolution of the mother crystal. In contrast, for the core‐to‐core case, the growth of new crystal core and the dissolution of original crystal core will proceed simultaneously, but they are physically separated. Herein, the two mechanisms are elucidated in detail, with some typical examples from recent advances.
