Synthesis and Characterization of Polyamine Bicycles for Anion Binding
… This thesis details the interaction between anions, such as Br-, Cl-, and F- and a group of familiar Schiff base derived azacryptands. Often these systems are synthesized by tosylating i.e., protecting, the bridging amine sites to prevent them from undesirable interactions. Only after …

Synthesis of Tin Containing Calix[4]arenes and their Anion Binding Capabilities
… functionalities may be placed in order to design anion binding hosts of very specific dimensions and selectivities. The purpose of this research is to synthesize a ditopic species that has the ability to simultaneously complex anions and cations starting from the calix[4]arene skeleton. Starting …

A STUDY OF THE THERMODYNAMICS OF ANION BINDING TO HUMAN SERUM TRANSFERRIN
… transferrin indicates that certain inorganic anions alter the electronic environment of the ion centers of the protein by binding to specific anion sites. The binding of these anions (thiocyanate, perchlorate, adenosinetriphosphate, pyrophosphate, and chloride) is shown to occur pairwise with …

Binding and Detection of Anions Using Tripodal Hosts
The aim of this project was to investigate the anion-binding properties of a range of different receptor compounds. For the most part, the receptors reported here were tripodal in nature, wherein three hydrogen-bonding receptor groups, including amines, amides and ureas, are linked around a common …

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 …

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 …

Main Group Hydrogen-Bond Donors and Pyridyl Ligands for Supramolecular and Coordination Chemistry
… chapter we develop strategies for enhancing the anion binding properties of phosphazanes of the type [(RNH)(E)P(µ-NtBu)]2 (E = O, S, Se) which are bench stable, H-bond receptors that can be regarded as inorganic analogues of squaramides (a key class of organic anion receptor). We find that there …
