Abstract The selective binding of a substrate by molecular receptor to form supramolecular species involves recognition which rests on the information stored in interacting species. functions supermolecules cover recognition, as well catalysis and transport. In combination with polymolecular organization, they open ways towards devices for processing signal generation. development such requires design components performing given function (e.g., photoactive, electroactive, ionoactive,...

Beyond molecular chemistry based on the covalent bond, supramolecular aims at developing highly complex chemical systems from components interacting through noncovalent intermolecular forces. Over past quarter century, has grown into a major field and fueled numerous developments interfaces with biology physics. Some of conceptual advances future challenges are profiled here.

Recent advances in supramolecular coordination chemistry allow access to transition-metal complexes of grid-type architecture comprising two-dimensional arrays metal ions connecting a set organic ligands perpendicular arrangement generate multiple wiring network. General design principles for these structures involve the thermodynamically driven synthesis complex discrete objects from numerous molecular components single overall operation. Such ion combine properties their constituent and...

As the wind of time blows into sails space, unfolding universe nurtures evolution matter under pressure information. From divided to condensed and on organized, living, thinking matter, path is toward an increase in complexity through self-organization.

The reversible connection between sets of basic components allows the generation a large collection compounds constituted by all possible combinations that are potentially available. It makes virtual combinatorial libraries substances accessible through dynamic approach to chemistry. thermodynamically-driven evolution system leads actual expression constituent(s) present(s) best binding to/molecular recognition with target site (see diagram). general concept this methodology has wide...

Supramolecular chemistry is the study of structures and functions supermolecules that result from binding substrates to molecular receptors. Macropolycyclic receptors coreceptors have been designed form cryptate inclusion complexes display recognition towards spherical, tetrahedral, linear various kinds (metal cations, inorganic anions, organic or biological cations anions). Anion has led development anion coordination chemistry. Metalloreceptors simultaneously bind molecules metal ions;...

The simple reaction of a tris-bpy ligand strand with FeCl2 leads to the self-assembly unique cation 1, which consists torus formed by five ligands wrapped around FeII ions in double-helical fashion and closed central chloride ion. This structure, fivefold circular helicate, is helicate analogue DNA.

Abstract Chemistry is progressively unraveling the processes that underlie evolution of matter towards states higher complexity and generation novel features along way by self‐organization under pressure information. has evolved from molecular to supramolecular become adaptive chemistry constitutional dynamics, which allow for adaptation, through component selection in an equilibrating set. Dynamic systems can be represented weighted dynamic networks define agonistic antagonistic...

The self-assembly of the tris-bipyridine ligands BI and BII with iron(II) salts yields polynuclear complexes displaying structures cyclic double-helix type, termed circular helicates [n]cH (of order n). With in which bipyridine units ligand are connected by ethylene bridges, penta- or hexanuclear architectures [5]cH [6]cH obtained, depending on anion present during process. elongated oxypropylene bridges forms a tetranuclear helicate [4]cH, whose structure has been confirmed crystal...

Abstract Organic photochromic systems represent a starting point for the elaboration of light‐triggered molecular switching devices. The novel bispyridinium and bispyridine compounds 1 2+ 6 were synthesized as their uncyclized isomers from 3,5‐dibromo‐2‐methylthiophene in overall yields 43 44%, respectively. diarylethene photochromes 2 10 – 13 , substituted with electron donors acceptors, prepared 5‐methylthiophene‐2‐carboxaldehyde 21–32% yield. All found to exhibit pronounced properties....

On treatment with copper(I) ions, mixtures of the [oligo(2,2')-bipyridine] strands 2-5 yield spontaneously double helicates 2H(2)-2H(5) without significant crossover. Similarly, when a mixture two tris-bypyridine ligands 1 and 3a (containing different substitutions) is allowed to react nickel(II) only helicate 2H(3a) triple 3H(1) are formed. Thus, these systems undergo self-assembly self-recognition. The process represents self/nonself-discrimination involving preferential binding like metal...

Molecular and supramolecular diversity may be generated, respectively, by reversible, covalent or noncovalent self-assembly of basic components whose various potential combinations in number nature represent a virtual combinatorial library. This concept is applied to the induction inhibitors carbonic anhydrase (CA) reversible recombination aldehyde amine components. It found that presence CA favors formation those condensation compounds expected present strongest binding active site. The...
