Toward On-Demand Polymorphic Transitions of Organic Crystals via Side Chain and Lattice Dynamics Engineering.

While a general trend of the transition temperatures and thermal behaviors within the series is not evident due to the non-negligible chemical differences of the starting building blocks and the statistically low number of samples, an interesting trend emerges in the homologous series 6 – 8 with the transition temperatures increasing with the increasing length of the side alkyl chains from 8 to 12 carbons as expected due to the increase of the cohesive dispersive interactions with longer alkyl chains ( Figure S1 ). 35 To shed light on the coopera
