What does the term supramolecular mean?

What does the term supramolecular mean?

more complex
: more complex than a molecule also : composed of many molecules.

What are the supramolecular interactions give two examples?

Supramolecular structures are a result of various noncovalent interactions, including van der Waals interaction, electrostatic interaction, hydrogen bonding, hydrophobic interaction, coordination, etc., some of which are often cooperatively working in one supramolecular complex.

What is a supramolecular structure?

Supramolecular structures are large molecules formed by grouping or bonding smaller molecules. together. It belongs to the realm of nanoscience since it is often possible to develop molecules of a desired shape or functionality.

Which of the following is an example of a supramolecular?

Colloids, liquid crystals, biomolecular condensates, micelles, liposomes and biological membranes are examples of supramolecular assemblies. The dimensions of supramolecular assemblies can range from nanometers to micrometers.

Why supramolecular is important?

A supramolecular approach has been used extensively to create artificial ion channels for the transport of sodium and potassium ions into and out of cells. Supramolecular chemistry is also important to the development of new pharmaceutical therapies by understanding the interactions at a drug binding site.

What is Rotaxanes chemistry?

Rotaxanes are unique supramolecular structures in which a cyclic molecule is threaded onto an “axle” molecule and end-capped by bulky groups at the terminal of the “axle” molecule.

What does electrostatic interaction mean?

Electrostatic interactions comprise the attractive or repulsive interactions between charged molecules.

What type of bonding is present in supramolecular structure?

Whereas traditional chemistry concentrates on the covalent bond, supramolecular chemistry examines the weaker and reversible non-covalent interactions between molecules. These forces include hydrogen bonding, metal coordination, hydrophobic forces, van der Waals forces, pi–pi interactions and electrostatic effects.

What type of bonding exists in Supramolecules?

What is the scope of supramolecular chemistry?

Supramolecular chemistry is the chemistry of the intermolecular bond, covering the structures and functions of the entities formed by association of two or more chemical species.

What are Rotaxanes and Catenanes?

[n]Rotaxanes (Figure1A) are composed of a central dumbbell-shaped component encircled by nÀ1 trapped rings, while [n]catenanes (Figure 1B) contain n interlocked macrocycles. The prefix [n] indicates the number of me- chanically interlocked components, regardless of their identities.

What is Pseudorotaxane and its importance in synthesis?

Pseudorotaxanes are interlaced compounds in which a filamentous ligand is threaded through a cyclic one. Their one-step synthesis by self-assembly generally involves a ‘rings-and-strings’ strategy28 in which the interlaced product is not necessarily the most stable product of the assembly.

Is there a covalent bond in supramolecular chemistry?

But in supramolecular chemistry there does not exist a covalent bond, only non covalent interactions such as electrostatic interactions, hydrogen bonding, dispersion interactions and cation-pi interactions present between molecules or ions.

How does supramolecular chemistry differ from traditional chemistry?

Whereas traditional chemistry concentrates on the covalent bond, supramolecular chemistry examines the weaker and reversible non-covalent interactions between molecules. These forces include hydrogen bonding, metal coordination, hydrophobic forces, van der Waals forces, pi–pi interactions and electrostatic effects.

How are molecules held together in a supramolecular assembly?

A supramolecular assembly is a complex of molecules held together by noncovalent bonds.

How is the size of a supramolecular complex determined?

SCCs are discrete systems where selected metals and ligands undergo self-assembly to form finite supramolecular complexes, usually the size and structure of the complex formed can be determined by the angularity of chosen metal-ligand bonds. (a) Representative hydrogen bond patterns in supramolecular assembly.
