Halogen-bonded liquid crystals of 4-alkoxystilbazoles with molecular iodine: a very short halogen bond and unusual mesophase stability

Abstract

Complexes of molecular iodine with alkoxystilbazoles are liquid crystals with unusually high mesophase stability, predicated on an intermolecular I···I contact. Attempts to prepare analogous complexes with bromine led to an unexpected electrophilic substitution product.
