,Crown-Type Compounds — An Introductory Overview,al low molecular species is undeniable .. The chemistry of crown compounds is steadily increasing. About 250 original papers dealing with crown chemistry appeared only in 1980. New molecules with crown ether properties are constantly synthesized and new applications discovered.

Crown Compounds as Alkali and Alkaline Earth Metal Ion Selective Chromogenic Reagents, These compounds are designed to bring about specific color changes on the interaction with such metal cations as alkali and alkaline earth metals, thus being able to serve as probes or photometric reagents selective for these metal ions. The chromophoric groups can bear a dissociable proton (or pro

Photocontrol of Ion Extraction and Ion Transport by Photofunctional Crown Ethers,light is used as a trigger to cause subsequent life processes. We have been interested in the application of the phenomena to biomimetic systems. To imitate the fundamental functions of such photoresponsive systems, one has to combine within a molecule a photoantenna to capture a photon with a funct

Crown Compounds as Alkali and Alkaline Earth Metal Ion Selective Chromogenic Reagents,. The proton-dissociable crown ether dyes are especially suited for extraction photometric determination of alkali and alkaline earth metal ions. Similarly, the neutral crown ether dyes are potentially useful for such determinations in lipophilic homogeneous media.

Structural Chemistry of Natural and Synthetic Ionophores and their Complexes with Cations,e, a considerable number of model compounds were synthesized, above all the so-called polyether ligands which did not only help to understand the mechanism of action of the naturally occurring ionophores but also led to the rapid development of phase-transfer techniques in organic chemistry, to mention only one application.

Concept, Structure, and Binding in Complexation, At least one of the partners in most of the complexes of evolutionary chemistry is large and complicated enough to inhibit studies of its detailed structure and an analysis of the forces that control its shape.
