Clear as liquid crystals! New liquid-crystalline materials (see figure) were prepared by self-assembly driven by halogen bonding (XB) between a range of alkoxystilbazoles (XB acceptors) and derivatives of the 4-iodotetrafluorophenyl unit (XB donors). Despite the fact that the starting materials are not mesomorphic, the dimeric, halogen-bonded complexes obtained exhibited nematic and SmA phases, depending on the length of the alkyl chains present on the components.
