- Competing hydrogen-bond and halogen-bond donors in crystal engineering
-
In order to study the structure-directing competition between hydrogen- and halogen-bond donors we have synthesized two ligands, 3,3′-azobipyridine and 4,4′-azobipyridine, and co-crystallized them with a series of bi-functional donor molecules comprising

We developed and characterized four polyfluorinated bistolane derivatives. These compounds, which possess either two alkoxy substituents or an alkoxy group and a bromine atom in their two molecular terminals, were synthesized from readily available 4-alko

- Structure-function relationships in liquid-crystalline halogen-bonded complexes
-
New liquid-crystalline materials were prepared by self-assembly driven by halogen bonding between a range of 4-alkoxystilbazoles, 4-alkyl-, and 4-alkoxy-substituted pyridines as halogen-bonding acceptors, and substituted derivatives of4-iodotetrafluorophenyl as halogen-bonding donors. Despite the fact that the starting materials are not mesomorphic, the dimeric, halogen-bonded complexes obtained exhibited nemetic and SmA phases, depending on the length of the alkylchains present on the components. The modularity of this approach also led to new chiral mesogens starting from non-mesomorphic chiral compounds.
