What is meant by supramolecular polymers?
What exactly are supramolecular polymers? They are polymeric arrays of monomer units, held together by reversible and highly directional secondary interactions — that is, non-covalent bonds, such as hydrogen bonds. The resulting materials therefore maintain their polymeric properties in solution.
What is a supramolecular material?
Supramolecular materials are architectures consisting of molecules that are able to self-assemble into larger constructs (Lehn, 2002). Polymers as well as small molecules are able to form self-assembled structures.
What is living supramolecular polymerization?
In supramolecular polymerization, monomers bond through weaker reversible interactions, such as hydrogen bonds (H-bonds). Supramolecular polymerization usually proceeds through step-growth mechanisms (1), where both ends of each monomer are reactive and many smaller oligomers form before long polymers appear.
Is chromosome a supramolecular structure?
This study demonstrates that it is possible to explain this morphology by considering that chromosomes are self-organizing supramolecular structures formed by stacked layers of planar chromatin having different nucleosome-nucleosome interaction energies in different regions.
What are the main supramolecular interactions?
While 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 is supramolecular system?
A supramolecular system is an assembly of molecular subunits that are organized via intermolecular interactions that can be ionic or covalent. These interactions include hydrogen bonds, metallic coordination, hydrophobic interactions, Van der Waals forces and ionic interactions [1].
What is a supramolecular polymer?
By definition, supramolecular polymers are polymeric arrays of monomeric units that are connected by reversible and highly directional secondary interactions–that is, non-covalent bonds.
What is a macromolecule?
A macromolecule is a very large molecule with a diameter ranging from 100 to 10 000 angstroms. A macromolecule is often formed due to polymerization. Then they are called polymer molecules. A macromolecule is typically composed of a very large number of atoms chemically bonded to each other.
What is a polymer molecule?
Polymers have a molecular structure consisting chiefly or entirely of a large number of similar units bonded together. These units are called repeating units. These repeating units represent the monomers from which the polymer is made. Most of the times a macromolecule is formed due to polymerization. Then they are called polymer molecules.
