Question: Which Of The Following Is An Example Of A Supramolecular?

What is meant by supramolecular?

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

Is MOFs supramolecular?

Metal-organic frameworks (MOFs) are periodic porous architectures that are made by linking inorganic and organic units with strong bonds1,2,3,4,5,6,7,8. … With this strategy, crystalline supramolecular and hydrogen-bonded organic frameworks have been constructed as porous materials for gas adsorption38,39.

What are 3 examples of molecules?

What is supramolecular scale?

Whereas traditional chemistry deals with the construction of individual molecules (1–100 Å length scale) from atoms, supramolecular chemistry deals with the construction of organized molecular “arrays” with much larger length scales (1–100 nm).

What is supramolecular approach?

A supramolecular assembly is a complex of molecules held together by noncovalent bonds. … Thus they allow access to nanoscale objects using a bottom-up approach in far fewer steps than a single molecule of similar dimensions. The process by which a supramolecular assembly forms is called molecular self-assembly.

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 is supramolecular chemistry PDF?

Abstract. Supramolecular chemistry refers to the study of supramolecular assemblies. Traditional chemistry generally focuses on the covalent bonding but supramolecular chemistry monitored by weak interactions of noncovalent bonds; exist extensively in numerous vital biological processes.

Who defined the concept of supramolecular chemistry?

6.07. 12.3 Tetrazoles in Supramolecular Chemistry and Nanotechnology. Lehn formulated the concept of ‘supramolecular chemistry’ as a science dealing with complex molecules capable of self-organization. Classic examples of such molecules are DNA, RNA, and also enzymes and some peptidomimetics.

What is host guest interaction?

Host–guest interactions involve two molecules or materials that can form complexes through unique structural relationships and noncovalent binding. Also referred to as molecular recognition, this type of interaction is widely found in biorecognition processes, such as enzyme–inhibitor and antigen–antibody interactions.

Which of the following is an example of a Supramolecule?

Supramolecular chemistry, and template-directed synthesis in particular, is key to the efficient synthesis of the compounds. Examples of mechanically interlocked molecular architectures include catenanes, rotaxanes, molecular knots, molecular Borromean rings and ravels.

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 are supramolecular structures?

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.

What is Preorganization in supramolecular chemistry?

The principle of complementarity states that “to complex, hosts must have binding sites which can simultaneously contact and attract the binding sites of the guests without generating internal strains or strong nonbonded repulsions.” The principle of preorganization states that “the more highly hosts and guests are …

How supramolecular chemistry influences the fluorescence?

These intermolecular noncovalent interactions have been considered to be the main driving forces for fabricating fluorescent supramolecular polymers with AIE properties, and have an important influence on the fluorescence properties of the chromophores.

What is supramolecular architecture?

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.
