J. M. Lehn: „Supramolecular chemistry is the chemistry of the intermolecular bond, covering the structures and functions of the entities formed by the association of two or more chemical species” F. Vogtle: „In contrast to molecular chemistry, which is predominantly based upon the covalent bonding of atoms, supramolecular chemistry is
Three different squaraine tethered bichromophoric podands 3a?c with one, two, and three oxygen atoms in the podand chain and an analogous monochromophore 4a were synthesized and characterized. Among these, the bichromophores 3a?c showed high selectivity toward alkaline earth metal cations, particularly to Mg2+ and Ca2+ ions, whereas they were optically silent toward alkali metal ions.
A method for the synthesis of cyclobutane-containing benzocrown ethers by the template photocycloaddition of the corresponding chalcone-podands in solutions was developed. It was shown by X-ray diffraction analysis, 1 H and 13 C NMR, and UV spectroscopy that the intramolecular [2?+2?] photocycloaddition (PCA) is stereoselective with the

Encyclopedia of Supramolecular Chemistry (Online/Print Version) [Jerry L. Atwood, Jonathan W. Steed] on Amazon.com. *FREE* shipping on qualifying offers. The two-volume Encyclopedia of Supramolecular Chemistry offers authoritative, centralized information on a rapidly expanding interdisciplinary field. Supramolecular chemistry is introduced, together with a brief description of its origins and early references to the field. from simple hydrogen bonding molecules to more complex macrocycles such as calixarenes, crown ethers, podands, cyclophanes and cryptands.

A series of podands based on two or three hydrogen bonding “arms” situated in mutually ortho, meta, or para relationships about an aryl core have been prepared, and their affinities for simple inorganic anions were measured. Of the two-arm hosts the meta compound and to a lesser extent the ortho host exhibit a cooperative anion binding effect.

of supramolecular chemistry.[4] Specifically, the field of Fig. 4 The application of molecular receptors to achieve supramolecular control of the [2 + 2] photodimerization in the solid state. Control of reactivity using (a) resorcinol and (b) a crown ether, and (c) the targeted solid-state synthesis of a [2.2]paracyclophane using a resorcinol.
The term supermolecule (or supramolecule) was introduced by Karl Lothar Wolf et al. (Ubermolekule) in 1937 to describe hydrogen-bonded acetic acid dimers. The study of non-covalent association of complexes of molecules has since developed into the field of supramolecular chemistry.The term supermolecule is sometimes used to describe supramolecular assemblies, which are complexes of two or
