Supramolecular chemistry actually represents a fairly simple concept.“In contrast to molecular chemistry, which is predominantly based on the covalent bonding of the atoms, supramolecular chemistry is based up on intermolecular interactions, i.e on the association of two or more building blocks, which are held together by intermolecular forces”. When molecules get larger, they have the ability to stick together and that allows the formation of larger assemblies of molecules that are not bonded to one another but stick together and organize themselves, just like the pieces of the puzzle. Supramolecular chemistry is the domain of chemistry that deals with the forces that will allow them to stick together, which may include hydrogen bonding, metal coordination, hydrophobic forces, van der Waals forces pi-pi interactions and electrostatic effects. Important concepts that make this domain of chemistry very special include molecular self-assembly, folding, molecular recognition, host-guest chemistry, mechanically-interlocked molecular architectures, and dynamic covalent chemistry.
1.1.1 Supramolecular self-assembly:
Supramolecular self-assembly has wider applications in sciences (like Genetic engineering, Pharmaceutical research and Bio-Nanotechnology) that deal with living systems. Living systems stand out as a typical example for supramolecular assemblies.
Individual cells spontaneously self assemble in to functional entities when they divide, and learning the rules of self assembly, that gives rise to functionality will help the scientific community to find a variety of applications.
Most of the infectious diseases are dependent on the ability to assemble in to functional entities. Functional viruses are a self-assembly process...

....U398p_ldU0cThe design porphyrin based receptors for the recognition of anions is a difficult area in Supramolecular chemistry.Recently a lot of research have been started and the results obtained so far are very promising.
Design of Porphyrin Anion Receptors:

Considering a design is of utmost important before an anion receptor can be synthesized.The receptors must be preorganised for substrate binding. The amide and urea groups should be organized in such a position allowing them to converge the anion.Improved binding results by providing a maximum number of hydrogen bonding contacts for the anionic guests.The design should be in such a way that it makes the compound synthetically accessible in large yields so that various studies can be carried out.

Essay Nuclear Chemistry - Types of Radiation: • List the three types of Radiation and describe conditions under which each case occurs. Alpha, Beta, Gamma. Alpha radiation/emission - Alpha particles are the nuclei of a Helium atom 42He. Consisting of two protons and two neutrons, positively charged. The nuclei are ejected from heavy, unstable nuclei so as to remove excess protons and neutrons. However, the formed nuclei may still be radioactive in which even further decay will occur. Alpha emissions occur in nuclei with atomic numbers greater than 83....   [tags: Chemistry]

Chemistry of Taste and Smell Essays - The human body does amazing things on a daily basis. All the senses that the body uses consists of nerves, neurotransmitters and the brain decodes the messages that was received. Smell is the passing of odorants through the nose, received by the olfactory cells, and are sent directly to the brain. Taste is the weakest of the five senses but it is the sensory function of the central nervous system( The Science of Taste and Smell). We taste and smell things every day but little do most people know that these two senses work together to make life even more satisfactory....   [tags: Chemistry Essays]

Chemistry before Technology: Alchemy Essay - ... According to the New York Times article “The Magical Origins of Modern Chemistry” alchemy was a philosophy and practice that sought to understand the nature of matter. Because of the alchemist they were able to make porcelain, pigments, perfumes, gunpowder, and pharmaceuticals. Before technology was brought into chemistry it took longer for scientist to discover certain items and chemical compounds and it took them longer to figure out how to do certain things. Before there were phones and computers scientist and chemists could not share their data with others in hope to gain more knowledge and ideas on how to make chemical reactions work....   [tags: history of chemistry, medical research] 800 words

Chemistry and Synaptic Transmitters Essay - Chemistry and Synaptic Transmitters The most common psychoactive substances can be divided into depressants (i.e., alcohol, sedatives, hypnotics), stimulants (i.e., cocaine, amphetamines, ecstasy), opioids (i.e., morphine and heroine), and hallucinogens (i.e., PCP, LSD, cannabis). The brain has different effects to different psychoactive substances. They bind to different receptor types, and can increase or decrease the activity of neurons through several different mechanisms. Consequently, these psychoactive substances have different behavioral effects, different rates of development of tolerance, different withdrawal symptoms, and different short-term and long-term effec...   [tags: Chemistry Science Scientific Essays]
