crystalline phases (B- and G-phases) were found for a twistable π-conjugated molecule, CN-DSB, condensed from its solution. We investigated the structural evolution at the molecular and supramolecular levels as the crystalline phase transforms from the B-phase to G-phase under varied temperature or pressure. The intermolecular interactions were undermined before phasetransition as the B-phase crystal was
