What´s Supramolecular Chemistry

3 Molecular Recognition: "Molecular Recognition Intentionally Selective Binding" Molecular recognition is a very specific interaction between molecules, and this interaction is believed to occur only between molecules complementary to each other. Factors that lead to complementarity between molecules are the shape of the surface of the two molecules, hydrogen bonding between molecules, ion-ion and ion-dipole interactions, and dispersive power. 4 The anion-recognizing anion has a net negative charge and exists in everywhere because it has a bonding pattern.

One of the problems faced by nanotechnology is how to assemble atoms and molecules into smart materials and working equipment. Supermolecular chemistry is a very important tool. Supramolecular chemistry is a chemical outside the molecule that is designed to self-assemble into a larger structure. In this case, biology is the place to look for inspiration. Cells and their fragments are made from self-assembling biopolymers such as proteins and protein complexes. One of the things being sought is the synthesis of organic molecules by adding organic molecules to the ends of complementary DNA strands (for example, A - - - B) in which the molecules A and B are attached to the ends is there. Together, the complementary DNA will join the hydrogen bonds into a double helix = === AB, removing the DNA molecule and separating the product AB.

Since its founding, shared chemistry has dominated the field of biomaterials. However, the advent of supramolecular chemistry has begun to improve understanding of biology and the ability to create accurate physiological structural materials. Nobel laureate winner Jean-Marie Lehn deeply states the supramolecular interaction "Beyond molecular chemistry". Self-assembly (5) In vivo, supramolecular biological signals indicate, for example, native extracellular matrix (ECM) interactions including receptor-ECM interactions and heparin binding proteins. In this way, biomolecules that interact via supramolecular interaction can be treated by means of controlled delivery (6) including cyclodextrin mediated small molecule chelation (7) or biomimetic electrostatic protein-matrix interaction (8) Has become

Supramolecular polymers consist of monomers that do not covalently interact. Common interactions include hydrogen bonding, metal coordination, and van der Waals forces. Mechanical stress in supramolecular polymers leads to the destruction of these specific noncovalent interactions, resulting in monomer separation and polymer degradation. In essential systems, the material itself can restore its integrity. While extrinsic methods are usually autonomous, endogenous systems often require exogenous induction for healing (eg, thermomechanical, electrical, light stimulation, etc.). Five major essential self-healing strategies can be distinguished. The first is based on reversible reactions and the most widely used reaction schemes are based on Diels-Alder (DA) and Reverse Diels-Alder (rDA) reactions.
