Halogen-bonding-triggered supramolecular gel formation.
Supramolecular gels are topical soft materials involving the reversible formation of fibrous aggregates using non-covalent interactions. There is significant interest in controlling the properties of such materials by the formation of multicomponent systems, which exhibit non-additive properties emerging from interaction of the components. The use of hydrogen bonding to assemble supramolecular ...
متن کاملSelective catechol-triggered supramolecular gel disassembly.
Supramolecular gels formed by an isonicotinic acid derivative in toluene are selectively disassembled in the presence of catechol. The results represent a unique example of molecular recognition associated to gel rupture which is of interest, for example, in controlled drug release applications.
متن کاملA systematic structural study of halogen bonding versus hydrogen bonding within competitive supramolecular systems
As halogen bonds gain prevalence in supramolecular synthesis and materials chemistry, it has become necessary to examine more closely how such interactions compete with or complement hydrogen bonds whenever both are present within the same system. As hydrogen and halogen bonds have several fundamental features in common, it is often difficult to predict which will be the primary interaction in ...
متن کاملHalogen Bonding in Crystal Engineering
The structural features of a molecule are determined by the covalent bonds within the molecule. Modification of the structure requires the breaking and creation of covalent bonds. Similarly, the intrinsic reactivity of a molecule arises from the covalently bonded functional groups and active sites on a molecule. Again, changing the properties requires modifications of the covalent bonds. Even i...
