Figure 7
Single-crystal-to-single-crystal polymorphic transition in ditBu-BTBT from the LT to the HT form, showing (a) the mol­ecular structure of ditBu-BTBT, (b) the order-to-disorder transition of the side –ditBu groups and (b)/(d)/(e) the three isolated conformations of the HT disordered phase. (f) The change in the herringbone dihedral angle in the (f) LT and (g) HT forms. H atoms have been omitted for clarity and better presentation. (h) Overlay of the unit cells and significant changes of the unit-cell parameters before and after the polymorphic phase transition (Chung et al., 2018aBB24).
