Exploiting our know-how in liquid crystals: strategies to benefit from mesogens’ supramolecular interactions

 

With the aim of understanding the intermolecular interactions that bring together certain molecules to form functional assemblies, liquid crystals (LC) constitute a paradigmatic example of self-assembling systems, since liquid crystalline molecules provide outstanding examples of supramolecular organizations. Mesogenic molecules can self-arrange and orient into architectures that define the final properties of the material. In addition to the information about self-organizational abilities, mesogens can also encode optical, electronic or magnetic properties of technological interest that can be transferred to a variety of functional thermotropic liquid crystalline organizations. Moreover, the aggregation of these molecular building blocks in liquid media provides materials with features similar to those of LC, constructed from a wide variety of chemical structures and with tunable properties.

The aim of this presentation is to highlight that the acquired knowledge from the LC field and the potential to develop a new generation of functional materials could be further exploited in other varieties of supramolecular materials using the same molecules in liquids. This may open up new processing alternatives and applications for supramolecular functional materials. For this purpose, representative examples that belong to two different molecular geometries, namely discotic and bent- ore mesogens, have been selected [1, 2].
