A simple and effective procedure to incorporate strongly-emitting inorganic clusters into nematic liquid crystals has been reported by a team from France. By combining the supramolecular paradigms of host–guest chemistry and electrostatic interactions the team have overcome previously insurmountable limitations of liquid crystalline materials.

A strategic design based on the use of asymmetrically 1,3-alkyloxyphenyl substituted β-diketonate ligands towards the BF2 group allowed us to find unsymmetrical compounds that, in addition to a high photoluminescent quantum yield, possess a liquid crystal behaviour, which is related to the presence of the banana-shaped liquid crystal mesophases B1.

With the exception of one compound containing terminal hydroxyl groups all compounds presented a wide thermal range and stable columnar liquid crystalline phase, characterized by differential scanning calorimetry, polarized optical microscopy, and X-ray diffraction (XRD) techniques.

All of the compounds showed high thermal stability and strong blue photoluminescence in solution and in solid films.
