Facile synthesis and supramolecular chemistry of hydrogen bond/halogen bond-driven multi-tasking tectons.
نویسندگان
چکیده
Hydrogen bonds and halogen bonds can be used as synthetic vectors without structural interference as long as the primary molecular recognition events are designed around a careful combination of geometric and electrostatic complementarity. In addition, a one-step procedure for the synthesis of tectons equipped with powerful hydrogen- and halogen-bond donors is presented.

Connectivity and Topology Invariance in Self-Assembled and Halogen-Bonded Anionic (6,3)-Networks.
We report here that the halogen bond driven self-assembly of 1,3,5-trifluorotriiodobenzene with tetraethylammonium and -phosphonium bromides affords 1:1 co-crystals, wherein the mutual induced fit of the triiodobenzene derivative and the bromide anions (halogen bond donor and acceptors, respectively) elicits the potential of these two tectons to function as tritopic modules (6,3). Supramolecula...
متن کاملAb Initio Studies on the Interplay between Unconventional B•••X Halogen Bond and Lithium/Hydrogen/Halogen Bond in HB(CO)2•••XCN•••YF (X = Cl, Br; Y = Li, H, Cl) Complexes
In this paper, ab initio calculations were performed on the ternary complex formed by HB(CO)2, XCN (X = Cl, Br) and YF (Y = Li, H, Cl). In these complexes boron act as a non-classical electron donor to form a unconventional halogen bond. The cooperative effect between the B•••X halogen bond and lithium/hydrogen/halogen bond was investigated. The calculated results show that the B•••X and N•••Y ...
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 کاملSupramolecular self-assembled network formation containing N···Br halogen bonds in physisorbed overlayers.
The formation of a halogen bonded self-assembled co-crystal physisorbed monolayer containing N···Br interactions is reported for the first time. The co-crystal monolayer is identified experimentally by synchrotron X-ray diffraction and the structure determined. Density functional theory (DFT) calculations are also employed to assess the magnitudes of the different interactions in the layer. Sig...
متن کاملHalogen-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 ...
