    • The diffuse scattering at d, 0.48 nm, associated to the mean distance between the fluid alkyl chains has its maximum on the meridian (see Figure 8b and S6b, Supporting Information, This might indicate some preference of the fluid alkyl chains to be organized parallel to the long axis of the columns, which could be the result of the changed conformational equilibrium due to the direct connection of the alkyl chains to the aromatic cores. A preferred organization of the alkyl chains parallel to the columns would provide a stronger segregation of alkyl chains and aromatic cores, because in this case a sliding of the molecules parallel to the columns short axes should be restricted. This means that the interfaces between aromatic cores and alkyl chains should become sharper and there is an improved packing of the aromatic cores which (together with the restrictions provided by the twisted conformation of the aromatic cores) should improve the overlapping of the it systems along the colum

    • In the crystal structure see ref, 17a, the intramolecular Cl-Cl distance at the same side of PBI molecule is 3.1 Å and the nearest intermolecular Cl-Cl distance is 4.2 Å. In the LC phase, the Cl atoms could be in close contact and form ribbons that are running parallel to the columns. The Cl-Cl interaction might contribute to the liquid crystallinity of 3a. Recently, a series of columnar mesophases were reported for indene and pseudoazulene compounds with rigid aromatic core which contain polarisable atoms such as Cl, instead of alky chains, as the soft moieties. See: S. Basurto, S. García, A. G. Neo, T. Torroba, C. F. Marcos, D. Miguel, J. Barberá, M. Blanca Ros, M. R. de la Fuente, Chem. Eur. J. 2005, 11, 5362-5376
