H-bonded complexes containing 1,3,4-oxadiazole derivatives: Mesomorphic behaviour, photophysical properties and chiral photoinduction

Two series of new V-shaped acids derived from 1,3,4-oxadiazoles are described. These acids were used to prepare supramolecular complexes through hydrogen bonding with 2,4-diamino-6-dodecylamino-1,3,5-triazine in a 3:1 ratio, respectively. The formation of the complexes was studied by infrared and NMR techniques. The thermal behaviour and mesomorphic properties of all the complexes were investigated by polarized light optical microscopy, differential scanning calorimetry and X-ray diffraction. Hexagonal and rectangular columnar mesophases were observed for all complexes at room temperature, without evidence of crystallization. The results of circular dichroism studies allowed us to propose that in the liquid crystalline state these materials adopt a helical columnar organization and this chirality can be controlled by irradiation with CPL. Furthermore, the complexes display strong blue luminescence in solution and in the mesophase. the Partner Organisations 2014.

Orthogonal action of noncovalent interactions for photoresponsive chiral columnar assemblies

(Figure Presented) Making a stack: Helical columnar architectures are prepared by a hierarchical self-assembly process involving H-bonding, π-π, and ion-dipole interactions (see picture). The strategic combination of these supramolecular interactions within mesomorphic systems yields materials in which photoinduced chirality and the incorporation of ions can be used to design multifunctional liquid crystals.

From small building blocks to complex molecular architecture

We describe a synthesis of a dendrimer-like amphiphile containing a flat rigid core and 12 hydrophobic and hydrophilic arms. We employ a modular approach based on stepwise protection chemistry starting from simple building blocks. The key feature of this approach is the absence of a polymerization step, which makes it applicable for linear monofunctionalized precursors of any kind. This strategy also allows for precise control of the number of arms and ensures their alternating arrangement.

Supramolecular assemblies of starlike and V-shaped PB-PEO amphiphiles

A star is born in the form of a polybutadiene-poly (ethylene oxide) amphiphile 1. The molecule exhibits remarkable self-assembly properties: it forms regular and reverse micelles in water and hexane, respectively. Comparison of 1 with a V-shaped precursor
