Cation-dependent photochromic properties of novel ditopic receptors

Properties and Application of a Novel Unsymmetrical Photochromic Diarylethene

Ion-pair Recognition by Ditopic Macrocyclic Receptors

Over the past thirty years, a large number of macrocyclic receptors have been synthesized and evaluated for their abilities to bind cations. More recently, increased attention has been directed towards receptors for anions. Many of these synthetic receptors are uncharged molecules and operate in organic solvents. Under these conditions the target salts exist as associated ion-pairs which can hi...

CATION UPTAKE PROPERTIES OF CALCIUM ALUMINOSILICATE

In this study, the effect of different parameters such as time and temperature of calcination and milling on the formation of calcium aluminosilicates was investigated. Raw materials used in this study were calcium carbonate and kaolin in high purity. Powder X-ray diffraction patterns were obtained from all samples after heat treatment at various temperatures and times. To study the microstruct...

Polyfunctionalized macrocycles demonstrate enantioselective and ditopic binding properties.

A pair of enantioselective, ditopic macrocycles is described; the receptors bind chiral ammonium cations in a manner that depends on the stereochemistry of the cation as well as the nature of its counter anion.
