“…Taking into consideration the dimension of the hydrogen-bonded supramolecular complex Z , Z , Z -TCS–MPBI (Scheme S3) and the X-ray-determined lattice parameter, a possible molecular packing structure is depicted in Figure d, while other cases cannot be precluded due to the lack of a well-aligned sample to give additional X-ray scattering information. In contrast to the helically stacked columns by star-like mesogens, , the strong π-stacking ability between discotic PBI moieties around the TCS core may dominate the assembly process to adopt such a weakly interdigitated structure with minimized interfacial energy and maximized nanosegregation of each component including the TCS core, PBI skeleton, and aliphatic segments. , In addition, the density (ρ) was calculated on the basis of the parameter measured by X-ray analysis by using the relationship ρ = ( M · Z )/( N A · V ), where M is the molar mass of the supramolecular complex, Z is the number of molecules in the unit cell, N A is Avogadro’s number, and V is the unit cell volume. The density was calculated to be 0.94 g cm –3 for this hexagonal columnar structure, which was reasonable for common organic compounds, and thus supported the formation of a hydrogen-bonded supramolecular complex and validated such a molecular packing manner.…”
