Hydrogen-bond driven assembly of a molecular capsule facilitated by supramolecular chelation.

چکیده
Resorcinarene-based cavitands functionalized with acetamido groups capable of self-complementary hydrogen-bond interactions, were synthesized in order to construct supramolecular capsules. The 1,3-bifunctionalized cavitand produced a polymeric assembly, whereas the tetra-functionalized analogue yielded a discrete capsule held together via N-H···O hydrogen bonds. The ethynyl species attached to the rim of these host molecules deepen each cavitand and expands the volume of the resulting capsule.

Coding a coordination-driven self-assembly via a hydrogen bond-directed solid-state synthesis: an unexpected chiral tetrahedral capsule.
An achiral ligand, synthesized in the solid state via a coded hydrogen bond-directed organic synthesis, self-assembles with Cu(II) ions to form a chiral tetrahedral capsule that hosts an anion as a guest.
متن کامل2D Supramolecular networks of dibenzonitrilediacetylene on Ag(111) stabilized by intermolecular hydrogen bonding.
The two-dimensional (2D) surface-directed self-assembly of dibenzonitrile diacetylene (DBDA) on Ag(111) under ultrahigh vacuum (UHV) conditions was investigated by combining scanning tunneling microscopy (STM), X-ray photoelectron spectroscopy (XPS) and theoretical simulations based on density functional theory (DFT) calculations. The molecule consists of two benzonitrile groups (-C6H4-C[triple...
متن کاملQuantum Chemical Investigations on C14C10-Branched-Chain Glucoside Isomers Towards Understanding Self-Assembly
Density Functional Theory (DFT) calculations have been carried out using a Polarizable Continuum Model (PCM) in an attempt to investigate the electro-molecular properties of branched-chain glucoside (C14C10-D-glucoside) isomers. The results showed that αconfiguration of pyranoside form is thermodynamically the most stable, while the solution should contain much more β...
متن کاملHigh-definition self-assemblies driven by the hydrophobic effect: synthesis and properties of a supramolecular nanocapsule.
High definition self-assemblies, those that possess order at the molecular level, are most commonly made from subunits possessing metals and metal coordination sites, or groups capable of partaking in hydrogen bonding. In other words, enthalpy is the driving force behind the free energy of assembly. The hydrophobic effect engenders the possibility of (nominally) relying not on enthalpy but entr...
متن کاملProgramming supramolecular assembly and chirality in two-dimensional dicarboxylate networks on a Cu(100) surface.
We report a comparative study on the 2D self-assembly of two related ditopic benzoic acid species, which have similar shape and endgroups but different backbone symmetry. High-resolution scanning tunneling microscopy data reveal how the symmetry information of molecular building blocks is readily expressed in the resulting chiral or nonchiral supramolecular networks. The underlying square Cu(10...
