Towards Responsive Squaramides: Anion Recognition, Sensing, and Transport
Anions play a crucial role in both biological and environmental contexts to such an extent where the absence or the overabundance of anions can lead to severe health implications and environmental concerns. The recognition of the universal significance of anions has led to an explosion of research …

Neutral receptors for anion recognition: synthesis, selectivity studies and transport properties
… urea groups that can function as selective anion receptors and efficient anion transmembrane transporters. Two new asymmetric ureidic receptors L1 (1-(1H-indol-7-yl)-3- (quinolin-2-yl)urea) and L2 (1-(quinolin-2-yl)-3-(quinolin-8-yl)urea), shown in Figure 1, have been synthesised and their …

New hydrogen bonding motifs for anion and neutral guest complexation
This thesis presents three different areas of anion or neutral molecule recognition chemistry. There is an extensive study of homoleptic and heteroleptic platinum(II) based receptors for anion recognition. The homoleptic receptor study revealed that urea ligands are more effective than …

Nature's way: the effects of hydrogen bond networks on acidities, catalysis, and molecular recognition
… bonds to better understand enzymatic reactions. Anion recognition abilities of synthetic hydrogen bonded receptors are studied to probe the role of hydrogen bonds in anion channels. At the same time, environmentally friendly green acids are developed and their catalytic reactivities in different …

An investigation into the molecular recognition and sensing of anions, especially of alkylcarbamates and related species
… thesis reports the synthesis and study of the anion recognition properties of a variety of synthetic organic and inorganic receptors. A series of known anion receptors containing a common urea and varying alkyl and aryl substituents have been investigated for their ability to bind the …

Formylated dipyrromethane based phosphate derivatives receptors
Anions are key components in many biological and industrial processes. They play crucial roles in both health and the environment. In many cases, it is important to control the concentration of anions or their removal in order to mediate their deleterious effects. Therefore, recognition of anions …

Induced-Fit Anion Sensing
Anions have many important roles in biological systems, as well as in the environment and as such there is significant interest in their binding and sensing. In induced-fit anion sensing, the binding of an anion causes a shift in the equilibrium of conformers of the molecule, which in turn may lead …

Relevanz und Nutzung von Anionen-pi Wechselwirkungen
… the use of a new intermolecular force between anions and electrondeficient arenes was investigated. In the last ten years the anion-pi interaction has gain a growing interest in the supramolecular community. It should be useful for the design of novel anion receptors. For this purpose the …
