New, halogen-bonded mesogens are formed as trimeric complexes of two molecules of alkoxystilbazole and one of 1,4-diiodotetrafluorobenzene. The pure complexes show only monotropic nematic phases, while mixtures show a enantiotropic nematic with a range of up to 11 °C. A possible correlation between nematic phase stability and halogen bond strength is suggested.
