新的卤素键合的间质是由两个烷氧二苯醚分子和一个1,4-二碘四氟苯分子组成的三聚体配合物。纯配合物仅表现出单向列相，而混合物表现出对映向列相，其范围可达11℃。向列相稳定性与卤素键强度之间可能存在相关性。
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 degrees C. A possible correlation between nematic phase stability and halogen bond strength is suggested.
