Scheme 1. Luminescent ionic mesogenic molecules with different anions and decorated by two or three alkyl tails.

This article describes highly luminescent ionic compounds in liquid and crystalline states, where a naphthalene moiety is conjugated to an imidazolium center decorated with two different lengths of alkyl chains.

Rare examples of bolaform ionic materials containing cyanometallates and their lamellar mesomorphic supramolecular architectures are characterized.
