In this work it is shown how the kinetics of a seeded crystallization process can be controlled through the application of an electric field. Not only were crystals made to dissolve at rates unique to the applied field, but also were forced to grow from an undersaturated solution, providing an additional control variable over crystal size distributions and crystallization dynamics. Analysis of the resulting crystal structure from the growth process reveals the formation of a previously unknown polymorph of glycine that maximizes the alignment of glycine molecules in the solid-state with the applied electric field, in agreement with the optical Kerr mechanism. In the newly discovered form, the glycine molecules pack with hydrogen bonding between the positively charged amino group and negatively charged carboxyl group in separate layers, with parallel C-N and C-O bonds within and between layers, making the dipole moment of each glycine molecule point directly down the applied electric field vector. This shows how applied fields can be used to stabilize and form hitherto unknown materials. Furthermore, the electric field is shown to direct the creation of needle like morphologies. Here, the glycine nanocrystals are observed to elongate and grow down the applied electric field vector. Through a temperature quench, the new form was stabilized from solid-state reversion to 𝛼-, 𝛽-, or 𝛾-glycine over a 5 ns simulation. These simulations present not only a novel control mechanism for growth and dissolution, but also novel polymorphic form production, showing how electric fields are predicted to be able to extend the landscape of accessible crystal structures, and unlock new solid-state material properties.
