Supramolecular chemistry refers to the branch of chemistry concerning chemical systems composed of a discrete number of molecules. The strength of the forces responsible for spatial organization of the system range from weak intermolecular forces, electrostatic charge, or hydrogen bonding to strong covalent bonding, provided that the electronic coupling strength remains small relative to the energy parameters of the component. 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.
Molecular machines are a class of molecules typically described as an assembly of a discrete number of molecular components intended to produce mechanical movements in response to specific stimuli, mimicking macromolecular devices such as switches and motors. Naturally occurring or biological molecular machines are responsible for vital living processes such as DNA replication and ATP synthesis. Kinesins and ribosomes are examples of molecular machines, and they often take the form of multi-protein complexes. For the last several decades, scientists have attempted, with varying degrees of success, to miniaturize machines found in the macroscopic world. The first example of an artificial molecular machine (AMM) was reported in 1994, featuring a rotaxane with a ring and two different possible binding sites. In 2016 the Nobel Prize in Chemistry was awarded to Jean-Pierre Sauvage, Sir J. Fraser Stoddart, and Bernard L. Feringa for the design and synthesis of molecular machines.

A single-molecule magnet (SMM) is a metal-organic compound that has superparamagnetic behavior below a certain blocking temperature at the molecular scale. In this temperature range, an SMM exhibits magnetic hysteresis of purely molecular origin. In contrast to conventional bulk magnets and molecule-based magnets, collective long-range magnetic ordering of magnetic moments is not necessary.

In chemistry and physics, LIESST is a method of changing the electronic spin state of a compound by means of irradiation with light.
Electromanipulation is a micro-material analyzing method mostly used for manipulations of biological cells that uses properties of diverse electric fields. In nanotechnology, nanomaterials are so small that they can hardly be directly mechanically manipulated. Hence, electric fields are applied to them to make field-induced movements or deformations. It is a recently developed technology and is still in progress of widening applications. Types of Electronmanipulation includes dielectrophoresis, electro-rotation, electro-deformation, electro-disruption, electro-destruction, electroporation, and electro-fusion. Diverse electromanipulations are achieved using various electric fields including AC(alternating current), DC(direct current), and pulsed(deliver high-energy discharges at very short periods) electrical fields. Electromanipulation of cells permits diverse cell manipulations with minimal mechanical contact between cells and device structures. Although predominantly used in cells, elctromanipulation also contributes to other scientific fields such as Hybridoma technology and nanoelectronic devices development.
Spin crossover (SCO) is a phenomenon that occurs in some metal complexes wherein the spin state of the complex changes due to an external stimulus. The stimuli can include temperature or pressure. Spin crossover is sometimes referred to as spin transition or spin equilibrium behavior. The change in spin state usually involves interchange of low spin (LS) and high spin (HS) configuration.

Didier Astruc carried out his studies in chemistry in Rennes. After a Ph. D. with professor R. Dabard in organometallic chemistry, he did post-doctoral studies with professor R. R. Schrock at the Massachusetts Institute of Technology Cambridge, Massachusetts, in the U.S. and later a sabbatical year with professor K. P. C. Vollhardt at the University of California at Berkeley. He became a CNRS Director of research in Rennes, then in 1983 full Professor of Chemistry at the University Bordeaux 1. He is known for his work on electron-reservoir complexes and dendritic molecular batteries, catalytic processes using nanoreactors and molecular recognition using gold nanoparticles and metallodendrimers.
Low molecular-mass organic gelators (LMOGs) are the monomeric sub-unit which form self-assembled fibrillar networks (SAFINs) that entrap solvent between the strands. SAFINs arise from the formation of strong non-covalent interactions between LMOG monomeric sub-units. As SAFINs are forming, the long fibers become intertwined and trap solvent molecules. Once solvent molecules are entrapped within the network, they are immobilized by surface tension effects. The stability of a gel is dependent on the equilibrium between the assembled network and the dissolved gelators. One characteristic of an LMOG, that demonstrates its stability, is its ability to contain an organic solvent at the boiling point of that solvent due to extensive solvent-fibrillar interactions. Gels self-assemble through non-covalent interactions such as π-stacking, hydrogen-bonding, or Van der Waals interactions to form volume-filling 3D networks. Self-assembly is key to gel formation and dependent upon reversible bond formation. The propensity of a low molecular weight molecule to form LMOGs is classified by its Minimum Gelation Concentration (MGC). The MGC is the lowest possible gelator concentration needed to form a stable gel. A lower MGC is desired to minimize the amount of gelator material needed to form gels. Super gelators have a MGC of less than 1 wt%.
The Weak-Link Approach (WLA) is a supramolecular coordination-based assembly methodology, first introduced in 1998 by the Mirkin Group at Northwestern University. This method takes advantage of hemilabile ligands -ligands that contain both strong and weak binding moieties- that can coordinate to metal centers and quantitatively assemble into a single condensed ‘closed’ structure. Unlike other supramolecular assembly methods, the WLA allows for the synthesis of supramolecular complexes that can be modulated from rigid ‘closed’ structures to flexible ‘open’ structures through reversible binding of allosteric effectors at the structural metal centers. The approach is general and has been applied to a variety of metal centers and ligand designs including those with utility in catalysis and allosteric regulation.

A chemiresistor is a material that changes its electrical resistance in response to changes in the nearby chemical environment. Chemiresistors are a class of chemical sensors that rely on the direct chemical interaction between the sensing material and the analyte. The sensing material and the analyte can interact by covalent bonding, hydrogen bonding, or molecular recognition. Several different materials have chemiresistor properties: semiconducting metal oxides, some conductive polymers, and nanomaterials like graphene, carbon nanotubes and nanoparticles. Typically these materials are used as partially selective sensors in devices like electronic tongues or electronic noses.
