What are supra molecules?
What are supra molecules?
The term supermolecule (or supramolecule) was introduced by Karl Lothar Wolf et al. The term supermolecule is sometimes used to describe supramolecular assemblies, which are complexes of two or more molecules (often macromolecules) that are not covalently bonded.
What are Supramolecules and give examples?
A supramolecular assembly is a complex of molecules held together by noncovalent bonds. 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.
What are the intermolecular forces in Supramolecules?
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.
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 the etymology of supramolecular?
English word supramolecular comes from English molecular, English supra- (Above, over, on top. Greater than, transcending.)
What are supramolecular devices?
Thus a supramolecular device is a complex system. made up of molecular components with definite individual properties. These properties are. intrinsic to a particular molecular component whether it is part of the device or not.
What is a simple definition of a molecule?
Listen to pronunciation. (MAH-leh-kyool) The smallest particle of a substance that has all of the physical and chemical properties of that substance. Molecules are made up of one or more atoms.
What is the meaning of supramolecular?
Definition of supramolecular : more complex than a molecule also : composed of many molecules : more complex than a molecule also : composed of many molecules
What is the importance of thermodynamics in supramolecular chemistry?
In addition, the dynamic nature of supramolecular chemistry is utilized in many systems (e.g. molecular mechanics ), and cooling the system would slow these processes. Thus, thermodynamics is an important tool to design, control, and study supramolecular chemistry.
What are the major interests in supramolecular chemistry?
One of the major interests in supramolecular chemistry is the design of structurally well-defined architectures with dynamic and stimulus-responsive properties. Dynamic and adaptive supramolecular materials that self-assemble from multiple components will find a range of applications in materials and medicines.
What is the molecular environment around a supramolecular system?
The molecular environment around a supramolecular system is also of prime importance to its operation and stability. Many solvents have strong hydrogen bonding, electrostatic, and charge-transfer capabilities, and are therefore able to become involved in complex equilibria with the system, even breaking complexes completely.
